Dear customer,the company BIKE FUN INTERNATIONAL would like to thank you for buying its product – a bike that is equipped with quality components from renowned companies. The mountain bike is suited forriding in terrain and, unless equipped with mudguards and lights, it is not meant for common riding on dirt paths. Both mountain and city bikes that are equipped with mudguards and lights are meantfor riding on dirt paths. Each bike is possible to be used only for the purposes that it was made for.For further maintenance we provide you with the following manual, which also contains the warranty certificate and the terms of warranty.The product was tested in the state testing laboratory No. 202 in Jablonec nad Nisou.The company BIKE FUN INTERNATIONAL, the producer of your new bike, wishes you a lot of excellent and safe kilometres.BIKE FUN INTERNATIONAL s.r.o.Štefánikova 1163742 21 Kopřivnicetel.: +420 556 492 792fax: +420 556 493 189info@bikefunint.comwww.bikefunint.comGeneral warningCycling can be hazardous even while maintaining the highest caution. Therefore, it is necessary to maintain your bike thoroughly as it reduces the risk of injury. This manualcontains a lot of warnings and cautions concerning the consequences of disregarded maintenance and/or technical checkup of your bike. Many of those warnings and cautionssay: “You can lose control and fall.” As the result of each such fall can be a serious injury, or even death, this warning should never be neglected. We recommend using a safetyhelmet of an approved type when riding the bicycle.2

THE FIRST 150 kmThe first 150 km can be defined as a warming up phase, in which the life of a cyclist is filled with emotions and eventful experiences from a new sport. On the other hand the operating reliabilityand the bike lifespan are being tested as well.WHY RUNNING-IN AND WHY EXACTLY 150 KM?A bit of theory never hurts. Everything during its operation respects a certain law regarding the number of defects, depending on the length of its usage. Mechanisms behave, more or less, properlyaccording to a so-called a tub curve of failure incidence, which has three fundamentally different operation periods. At the beginning, the numbers of defects rather sharply decrease, followedby a long period of steady low occurrence and in the end defects start to occur more often.The first phase is the running-in period, the second one can be marked as the optimal operation period. Long-term operation with a minimum amount of defects is the reward for our caringattention and maintenance. The operation period of higher supervision, expressed by the figure 150 km, can be viewed as a period suitable for the first guarantee revision setup based on serviceexperience and assuming that more expensive and operationally more burdened bikes will be more checked by their owners. Do not assume that the term “first guarantee checkup” means the sameas the day when someone has the first look at your bike. He might as well replace some parts, like handlebars for new ones, all of which would be at your expense. Even a life-long warranty doesnot cover ignored maintenance.WHAT TO WATCH FOR DURING THE RUNNING-IN PHASEEven if the bike was properly adjusted before the operation phase, the production technology of its parts and their assembly require a certain operation time to stabilize proper functions. Generallyspeaking, everything that moves and turns needs to find and smooth out its track, and everything that is firmly mechanically connected must settle down and create the necessary interfaces.By smoothing out rough contact surfaces the turning or skiddy placement will create clearance and the firm connections will loosen up.What does it mean? The pedals might be a bit stiff at the beginning but after some time they have a noticeable clearance. The same with the seat.... with which the height of the seat is difficultto set. This problem is usually solved by one-shot tuning of expensive parts with scoured tracks. On the contrary, the components with moulded and very often non-circular and surfaces not hardenough for bearings, are difficult to tune and the state of long-term optimal set up is sometimes practically impossible. Individual carefully watched places, where the ignored maintenance canhave a significant influence from the point of view of safe operation:Recommendation: if some parts or components of the bike get damaged during operation, replace them immediately!!! Use only the original spare parts purchased from authorised dealers!!!We recommend to have your bike checked at least once a year at regular intervals in authorised service workshops! In case of an accident we strongly recommend to have your bike professionallychecked in an authorised service.3

thin oils with teflon and a high ability to rise (get absorbed) inside (e.g. GT 85) or special lubricants for chains (Castrol). Classic machine oils appear to be markedly cheaper, but you would haveto literally rinse the chain with them, wipe the excess oil off the surface and yet it is almost impossible to avoid sludge from occuring. It is worth paying attention to the chain from the beginningto the end of its technical life. When you miss the time to exchange it, it is almost sure that you will have to exchange also the cassette and possibly the converters, too. (However, that will certainlynot happen during the first 150 km).And do not forget – if, for whatever reason, you have to disconnect the chain, every other place but the black pin is suitable. Black connection pins happen to have a larger diameter than the others.By forcing them out the hole in the element enlarges it so much that further pulling of the pin is hopeless regarding its reliable function and it is very probable that the chain will disconnect at thisplace again. Use the black pins for connecting only, when disconnecting always avoid them.TOOLS THAT ARE FUNDAMENTAL FOR YOU• socket head spanner 8, 6, 5, 4, 3, 2 • sided spanner 15, 10 (2x), 9, 8• sided slim spanners 17, 14, 13• spanners for headset 40, 36, 34 (2x according to measurements needed)• Phillip's screwdriver finer and bigger• set for mending inner tubes• assembly lever• inflation pumpExtended equipment• chain riveter HG• clamps or special spanners for cassettes• clamp for cranks (with relevant side spanner)• closed nut spanner 14(15) mm• detergent to release pinions 2x (whips)• centre fork• centre spanner• gauges for degradation of chain and pinionsA lot of service work and repairs require specialized knowledge and tools. Do not ever start with any adjustment on your bike if you have any doubts about your abilities to finish the mending.Non-thorough service can endanger your life or health or cause damage to your bicycle or to other people.BASIC INSTRUCTIONSFront fork:Bent or damaged forks should be replaced, do not ever repair them.Front wheel:The wheel should always be centered by tightening the nuts in the front fork. Screws must be tightened properly. The gear hub is sealed against humidity or dirt, but should be repeatedly checkedespecially after riding through demanding terrain. The wheel must be able to spin freely with only a small amount of friction or looseness.5

Therefore it is essential:1) Ask your dealer to help you with exact procedures on how to attach and detach the wheels2) Understand and apply correct techniques of fastening the wheels using fasteners3) Make sure before every ride that the wheel is safely fastened.Removing or damaging the fastening mechanism is very dangerous and can cause invalidity of the warranty, and moreover to lead to serious injuries or death.Incorrect setting of the fastening mechanism can cause the wheel wobbling or loosening, which can lead to serious injuries of death.4) Verify before every ride that the rim is not excessively worn. That could jeopardize your life or health and/or cause a damage on your bicycle or to other people.Rear wheel:The wheel must be positioned in the rear fork and properly tightened by safety nuts. The gear hub is sealed against humidity and dirt, but should be repeatedly checked especially after ridingthrough a demanding terrain. The wheel must be able to spin freely with only a small friction or looseness, which can jeopardize your life or health, and/or cause a damage on your bicycle or toother people.Therefore it is substantial:2) Ask your dealer to help you with exact procedures on how to attach and detach the wheels2) Understand and apply correct techniques of fastening the wheels using fasteners3) Make sure before every ride that the wheel is safely fastened.Removing or damaging the fastening mechanism is very dangerous and can cause invalidity of the warranty, and moreover to lead to serious injuries or death.Incorrect setting of the fastening mechanism can cause wheel wobbling or loosening, which can lead to serious injuries or death.Rim:Keep the rims in an undamaged and correctly centered state.Regularly check their state and the state of their degradation.The state of degradation:a) Safety system – degradation is indicated by the depth of the lengthwise line on the brake surface. In case the depth is minimum, do not use the rim anymore and ask your dealer for itsreplacement.b) RDA system – degradation or the damage on the rim is indicated by coloured liquid leaking from the inside of the rim. In such a case do not use the rim and ask your dealer for replacement.Centre composition:Check the centre composition regularly and always after riding in demanding terrain. The shaft must spin freely without side looseness. The safety ring must be tightened and the bearings welllubricated.6

Handlebar:Adapt them to your comfort and tighten up all the screws of the handlebar stem where the handlebar goes through the handlebar stem.The mark of the minimum pull-up must not be visible above the headset. Damage to the handlebars can cause losing control and falling down. Lifted-up handlebars can jeopardize your lifeor health and/or cause damage to your bicycle or to other people. We recommend screws on mounting handlebars to be tightened by 7Nm. If your handlebars are equipped with extensions (horns),we recommend to tighten them by 7Nm.Gear and derailleur:Keep them correctly set up. Shift gears only when you pedal and while riding up hill try to reduce the weight on your legs when changing gears (to reduce the tension on the chain), try to avoidthe impact on the rear derailleur.If your derailleur is set up incorrectly, do not ever gear to the smallest or the biggest gearwheel. It can cause the chain to block and then you can lose control and fall.Chain:• Regularly measure its stretching and replace it if necessary (approximately after 1 000km)• Lubricate it often and clean it with thin oil; wipe off excess oil with a cloth• The lifespan of the chain can vary according to the chain brand and according to the operation conditions.We recommend to exchange the chain in specialized service workshops.For one-speed bicycles it is necessary to keep a sufficient stretching of the chain. If it loosens up, the repeated stretching is needed. Stretch the chain by loosening the rear wheel nut and by pullingthe wheel outside you will stretch the chain again. Afterwards, tighten up the rear wheel nut again.Tires:Keep the tires pressured to the right volume, which is stated on the side of the tire casing. Use a hand or foot inflation pump. Check if the tires are properly positioned in the rim.Do not ever over-inflate the tire. The tire can stick out from the rim due to excessive pressure and that can cause damage to the bike and injury to the rider or other people, both pedestriansand on-lookers. Do not ever use air hoses at gas stations to inflate your bicycle.Cranks and pedals:Lubricate the pedals occasionally, especially after riding in demanding terrain. Do not try to straighten cranks or converters that are bent. After the first ride tighten up the crank screws, checkthe converter screws and pedal shafts. Do not ever continue riding if the crank (crank square) on the centre shaft or a pedal in the crank loosens. No claim for a complaint shall be applied onlooseness in cranks and pedals occurred by insufficient maintenance.7

Toe clips:Using toe clips requires a considerable extent of skills. If you do not manage it automatically, you will be required to concentrate to a large extent, which can reduce yourattention when riding and cause loss of control and falling. Practice using toe clips only outside away from dangerous and busy roads. Do not fasten toe clips if you feelunsure when using them. The foot pedals can be used only in combination with specially adapted shoes that fit into the pedals firmly. Riding requires perfect knowledgeof using the foot pedals, otherwise your attention when riding is distracted which can lead to loss of control and falling. Practice using the foot pedals only outside awayfrom dangerous and busy roads.Brakes:Warning: For bike models with brakes of the V type or other rim brakes, the braking surface of the rim can get worn. Therefore, it is necessary to pay attention to the rim and the brake wedges’degradation. You can find two types of indication of the rim degradation on our bike models:a) black indication line on the braking surface – if the indication line gets interrupted or erased due to degradation replace this rim immediately.b) SCR indication system – after the side of the rim gets worn the braking surface becomes deformed and the inside of the rim is damaged. The bike appears wobbly whereas the casing stayssafely positioned.reinforced rim siderimrim sideRecommended degradation of the braking surface 0.35 mm.brakewedge2 - 4 mmKeep the brake pads set up 2-4 mm from the rim. Check their degradation and if necessary replace them. Clean the oil or dirt accumulated on the rim and/or the brake shoes.Exact set up of the brakes is very important due to the extent of the brake lever movement, so that the full braking power can be used within this extent. If the full braking effect is not reachedwithin the brake lever extent, you can lose control leading to jeopardizing your life or health and/or cause damage to your bicycle or to other people.Caution: riding on wet surfaces is a lot more demanding than on dry ones. In this case the brake efficiency is reduced, and therefore, the cyclist should behave morecautiously.Control wires:Stretch the wires properly. Check them regularly, do not leave them loose and when worn, replace them. Do not make loops on the wires under any circumstances. Use aluminium end piecesagainst unraveling.8

Seat adjustment:Adjust the height and the angle to your comfort. Do not pull up the seat bar higher than the mark of the minimum insertion into the bike frame. If the seat turns in the frame, tighten the seat upby the fastening seat screw.If the seat is pulled up higher than the mark of the minimum insert it can break, followed by loss of control and falling. Make sure during any manipulation with the seatthat you adjusted it properly before riding, otherwise the seat can get damaged or it can cause loss of control and falling. Check it continuously and make sure that the seatis correctly adjusted.Riding with an incorrectly tightened seat can cause the seat to turn or move in such way, that you can loss control and fall.Therefore:1) Ask your dealer to advise you on exact procedures and techniques of correct seat adjustment.2) Understand and apply the correct techniques of fastening the seat.3) Before each ride first check that the seat is safely adjusted.Spotlights and Reflectors:Spotlights and reflectors should be mounted on the front fork, on the back side of pedals and on wheel wires. When damaged they should be replaced immediately.Riding during dusk, darkness and time of reduced visibility without suitable lights and reflectors is dangerous and can lead to serious injury or death.Frame:Repeatedly check possible damage in colour around frame connections. This can show you a bent or broken frame.Replace the bent or broken frame immediately, because other parts of the frame can be excessively strained which can cause the large danger of possible injury.Headset:Keep in mind to adjust the safety nut tightly, the fork should spin freely. Tighten the nuts and screws regularly as necessary. Repeatedly check damaged parts, composition of fork and placementof all parts.Unsuitable adjustment of the headset can influence abilities to drive and cause lose of control and all. Take your bike to your dealer and have them adjust the headsetprofessionally.The bike and its components have their lifespan and used materials get worn after some time. If the lifespan of some component expires it can suddenly fail and causeserious injury or death. When there are any signals indicating than the lifespan of any components are about to expire, it is essential to replace them immediately.An accident can prematurely end the lifespan of individual bike components. Those can then suddenly fail and cause loss of control and/or jeopardize your life or healthor cause damage to your bicycle or to other people.9

INSTALLING THE SEAT• Lubricate the seat and insert it into the frame. At least up to the line of minimal insertion. Tighten itby using the quick releasing mechanism, or a bolt. Before tightening it carefully study the prescribedtightening force.• Set up the angle of the seat and the levelness of the seat pad. Tighten up the seat lock.• Try to turn the seat to check its tightness.• NOTE: the seat can be adapted to be close or far from the handlebars. It is possible to reachby moving the seat on two tracks and securing it via the seat lock or firmly tightening the nut.Caution: Never set the seat above the line marked max. or stop.seat angleseat lockseatquick releasingmechanismINSTALLATION OF THE CARBON SEAT ROD• Never lubricate the seat rod with lubricating fat.• For proper mounting use only the special mounting paste FSA (dynamic assembly paste)INSTALLATION OF THE BRAKE CABLEFront brake cable:• Insert the end of the cable into the catch on the left brake lever.• Thread the cable by bowden and guideline cable, then tighten the shoulder brake screw• Press both jaws so that between the brake pads and the rim there is a 2-4 mm space• Then tighten the shoulder brake screw which holds the cable screw• Cut the excess cable so there is only about 40 mm left• Put the protective cap on the end of the cable and clamp it with pliers• Squeeze the cable protection cap by 20 NmRear brake cable:• The procedure is similar as mounting the front brake cable. For the rear brake cable the right brakelever is used.13

connecting cable(bowden cablewith wire )shoulder brakescrewbrake jawTRIMMING BRAKES (V-BRAKES)• Rim brakes call for occasional trimming, because tightening the cable and brake pads wears them down. The brake pads should beat a distance of 2-4 mm from the rims. Usually the the rear brake lever is mounted on the right and the front lever on the left partof the handlebars.• For better trimming the brakes, loosen the adjusting pin via the securing nut. In order that the brake pads are brought closer to the rim,turn the adjusting pin outwards. If the brake pads rub on the rim, turn the adjusting pin inwards. Check the brake trim.• The brake pads must not ever touch the tire casing. Protect against wearing it down.Caution: The left brake lever is the front brake and the right brake lever is the rear brake. If the rear brake in the rear gear hub goes againstpedalling, then the front brake lever is positioned on the left side..Be careful of the brake lever; it mustn’t go down to the grip when pulled. In that case, the brakes will become useless.It is necessary to trim it when setting up the brake cable.DISC BRAKEscrews no. 1 and 2 hold the segment in the lock (fork)screw no. 3 serves to catch the brake cablescrews no. 4 and 5 are trimmed screws for establishing the braking segment disc spacescrew no. 6 serves to trim the distance of the brake plates from the discCaution: The usefulness of the brakes can be tuned and set via the screw on the brake lever!!rear brake discsetting up theincline of thebrake stirrup tothe brake discssetting up thescrew for limitingthe space betweenthe brake disc andthe brake platescrew no. 2screw no. 5screw no. 6screw no. 3screw no. 4screw no. 1front brake discadjusting screw forlimiting the spacebetween the brakedisc and the brakeplate14setting up the inclinationof the brake stirrupto the brake disc

PEDAL INSTALLATION• Pedals are marked “R” and “L” on the front-side• Lubricate the pedal screws. - Screw the pedal marked “R” by turning to the right (the side with the converters). - Screwin the pedal marked “L” by turning to the left into the left lever.• Firmly tighten every pedal by using a no. 15 spanner• After riding about 50 km again tighten both pedals.WORK OF GEAR MECHANISM AND DERAILLEURThe gear mechanism system of your bike changes the gear ratio movement of the chain from one wheel to the next.The gears change only by pedalling forward. The smoothest movements are carried out by easy pedalling. The gearsystem is equipped with gear levers positioned on the handlebars. The right gear shifter moves the chain from 6-7-8or 9th rear gear wheel. Moving the gear shifter forward moves the chain from the smallest gear wheel (the hardestgear) to each higher gear wheel (easier gears). The left gear shifter moves the chain over the three front gear wheels.By moving the left gear shifter forward the chain is moved from the smallest converter to the largest. You will soon learnwhich position to use for various riding conditions. Only by working it out for yourself can you learn it well. Don’t tryto change gears with great pressure on the pedals. Never pedal backwards when changing gears. Your chain could fall off.Recommendation: Don’t use the gear shifter when there is an extreme crossing of the chain because then the whole gearmechanism suffers.handlescrew15 mm spanneradjusting screwlead chainpull wireDERAILLEUR• The lead chain must be in line with the converter and must be 1-3 mm above the teeth of the biggest converter.• When the derailleure lever (left) is in the rear position, check if the shifting wire is too loose or not.Looseness can be removed by undoing the screw with the wire anchor, by pulling the wire with pliers and then re-tightening the screw.• If the chain falls off from the largest converter in the direction of the right crank, tighten the upper screw foradjusting the derailleure one or two rotations. Carry out a test for changing gears again and adjust if necessary.converter leverderailleure leverGEAR• Lift up the rear wheel. Meanwhile turn the crank, pull the right lever back. The chain should be set on thesmallest rear wheel. If that doesn’t happen, turn the crank further and let the upper gear adjusting screw out,until the chain reaches the smallest wheel.15

• While turning the key, pull the lever completely forward, till the chain shifts onto the second smallest wheel. Pull the right lever backwards, the chain should smoothly shift onto the smallestwheel. While turning the key, pull the lever completely forwards. The chain should be set up on the largest rear wheel. If that doesn’t happen, turn the key further and turn the lower adjustingscrew on the rear gear shifter until the chain shifts onto the largest wheel.• While turning the key pull the lever back a bit, until the chain reaches the second biggest wheel.Pull the lever completely forwards, the chain should gently shift onto the largest wheel.Caution: For bicycles equipped with the index gear system – see a recommendedproducer for service.RE-SETTING WIRE• It can happen that the wire can be stretched and cause bad gear changing. Wire stretchingoccurs if the wire is loosened (when the gear levers are completely rearward). To get ridof theloosening, loosen the screw on the security wire, firmly pull the wire and repeatedlytighten the security screw.upper screw for adjustinggear shifterslower screw for adjustinggear shifterswire screwsecurity nutidle wheelflexible padalignment bowlball wreathstationary tapered rollerstationary tapered rollerball wreathgrooved coneADJUSTING THE BEARINGSYour mountain bicycle has four sets of bearings, which require adjusting and lubricating.1) headset2) central composition3) gear bearings of the wheel hub4) pedal bearingsLook over the bearings often, especially after riding in demanding terrain. The service intervals depend on the numberof kilometers ridden and the conditions of the riding. Although, there are effectively sealed bearings, no sealant used on thebicycle is water-proof. With a little skill and the proper tools you should be able to lubricate and tune the bearings yourself.16

Headset• Freely, but it shouldn’t be loose.• If the bearings need tuning, loosen the securing nut with a two-sided key. Tighten or loosen the adjustable wreath. Firmly tighten the nut and re-check it.• For lubricating the bearings, remove the handlebars. Take off the securing nut and adjustable wreath. Pull the fork from the frame and remove the two ball cages. Clean all parts with lubricationand look over the bearings for signs of wear and rust. Lubricate all parts again, mainly sufficiently cover the ring sealants. Install one ball cage on the fork. Insert the fork back into the frameand ensure that the ring has fallen on the bottom of the stationary wreath. Install the the second ball cage on the stationary cone.

Remove it from the front fork tube.• The handlebars are perpendicular to the front wheel.• Firmly tighten the screw of the headset and all the screws on the handlebars.• Check the final grip of the front wheel by taking it between your legs and trying to turn the handlebars.Your bicycle is implanted with a central composition encasement, it is only necessary to sometimes try if there is any looseness.This type of central composition is maintenance-free.Caution: the firm bowl has a thread.Gear hub• Take off the quick releasing mechanism• Unscrew the hub securing nut, spring pad and cone from one side of the hub. Pull the free hub from the core of the gear hub and remove the ball bearings.• Check if there is any damage or corrosion of the ball bearing track, (in which case take it out)• Lubricate the gear hub box and insert the bearings.• Return the hub back. Screw in the cone, until it reaches the ball bearing. Put back the spring pad and securing nut. Spin the hub. It should move without looseness or dragging.Re-adjust if it is necessary, tighten the securing nut. Mount the quick releasing mechanism.17

CENTRAL COMPOSITIONYour bicycle is equipped with a central composition encasement, it is necessary to sometimes try if it is loose.This type of central composition is maintanance-free.Caution: the hard bowl has a thread.Untouchable encasingof the central hubPEDALS• Turn each pedal and check if there is drag or loud noise. The pedal bearings seldom need maintenance, but whenit is necessary, read on.• Unscrew the pedal from the crank, remove the protecting cover, securing nut and sealing. Unscrew the cone andtake out the screw from the core of the pedal. Clean all parts with lubrication and ensure that there hasn’t beenany wearing down.Lubricate the bearing wreath and return the same number of bearings on each side. Screw in the cone again on thescrew, turn the screw so that you tighten the cone on the bearings. Put the key sealant and the securing nut. Checkfor looseness and dragging. Adjust the bearings and tighten the securing nut, mount the pedals on the cranks.Proper set upCHILDREN’S BICYCLESChildren’s bicycles are produced according to the European norms EN14765, which are designated for bicycleswith a maximum seat height of 435 mm and smaller than 635mm.Children’s bicycles are designated for use only on playgrounds, enclosed areas and only under the supervisionof a parent or care-taker. When a child is left unattended on a bicycle it can lead to serious injury or death.NEVER LEAVE A CHILD UNSUPERVISED!!!We emphatically recommend to always use a helmet of an approved type. The recommended load of a children’sbicycle is up to 25kg including any baggage. Before the first ride, please direct your attention to the correct set upof your new bicycle.Set the height of the seat so that the child comfortably reaches the handlebars and doesn’t sit too straightor oppositely, lie forward on the bicycle. Never raise the handlebars above the marked line (etched in and writtenSTOP, or MAX). Thoroughly explain to the child that the bicycle has anti-pedalling rear brakes. The front brake leveris positioned on the right side of the handlebars. Never brake with just the front brake.18

SPECIAL EQUIPMENT OF THE CHILDREN’S BICYCLEChildren’s bicycles are equipped from the producer with stabilizing wheels (training wheels). The stabilizingwheels serve to ease the ride of your child. Balancing the unbalanced young rider helps them better and moreeasily learn how to control the bicycle. The young rider can devote more time to riding the bicycle and learninghow to brake. It is necessary to check the stability of the wheels, whether unloosened screws tighten the bracesto the wheel, or if the wheels are sufficiently tightened to the brace. Untightened screws can cause incorrectfunctional stability of the wheels. It can lead to their loosening, which can be followed by a fall and possiblyinjuries or even death.The bike is equipped with an anti-pedaling brake for easier and more quality breaking of a young cyclist.It is necessary for further use of the bike to teach the child to brake the bike. Therefore, please spend enoughtime to teach your child before you are sure that he or she can stop the bike safely. The bicycle starts goingby moving the foot and the converter crank clockwise. To stop it is necessary to step on the converter crankin the other direction, i.e. counter-clockwise. The brake will start working to block the ride until the bike stopscompletely.tighten up withwrench 14/15Padded fork:If you want to keep the function of the padded fork perfect, regular maintenance is necessary, especially of the friction areas between the inner and outer pipe. The duster avoiding access of dirtto friction areas must not be damaged and must protect the full friction area. It is suitable to use a soft brush and warm soapy water to wash the fork. Caution: When washing, the water must notget between the inner and outer pipes of the fork. Dirt and water have an unfavourable influence on parts inside the fork.Lubrication of the forkIn the new padded fork there is a spring set with a layer of lubrication. It is necessary to always keep this layer of lubrication. The fork should be lubricated every time after riding in a humidenvironment (mud, wet sand, rain). If you do not have experience with maintaining and repairing forks, have professionals to do the service work.Fully padded frameMaintenance – after riding in muddy terrain it is necessary to clean all moving parts of the frame, this way you can prolong their lifespan. After every 150km check individual parts of the frame.If some parts get worn down, replace them, so the frame itself does not get damaged.
