ThoMAS KAMM ANSWErEd A FEW quESTIoNS ABouT our FuLL SuSPENSIoN BICyCLES. Since 2006 you have been working closely with STEVENS. You designed the Fluent and Glide series, two very successful and renowned full suspension bikes. What were your goals during the development of the enduro Ridge 2011? don’t you always have to combine opposites in suspension development? on the one hand you want comfort and great suspension characteristics, on the other you try to create stiff and efficient frames. How do you achieve a good balance between the two? That’s exactly the challenge! using a 4-pivot “horst- Link” (or: classic 4-pivot) already lays the foundation to a lightweight but stiff chassis. But then, especially with large suspension travel, you have to adjust the kinematics with great care so that there are no disadvantages for the suspension characteristics. I’m quite proud of the successful combination of all these properties on the STEVENS ridge. Both STEVENS Glide and Ridge 2011 feature a modified concept for the rear section, the Fluent now has 120mm of suspension travel in the back and the front. Is there a trend towards increased 22 suspension travel? What did you change? definitely, bikes in all categories are getting more suspension travel. But this is due to the fact that the kinematics are getting better and better, while variable suspension travel eliminates all disadvantages. Additionally, for 2011 STEVENS bicycles come with superb balance of the front and rear suspension, and the glide and the ridge feature stiffer frames and X12 through-axles. What’s the secret of the “Anti-Squat Kinematics” of the STEVENS full suspension bikes? Anti-squat means the ability to transform the pedaling force into propulsion without loss of energy. Reviews in magazines point out the difference between pedal bob and pedal feedback. What’s more relevant? This is a very difficult question, as there’s no right or wrong answer. The STEVENS rear sections follow the “as much as necessary and as little as possible” principle. The advantages of the first need to eliminate the disadvantages of the latter. Specifically: if I don’t want to have pedal feedback (this is only possible in one specific gear and with specific adjustment), I automatically get pedal bob. If I don’t want any pedal bob (i.e. 100% anti-squat), I will have to put up with some pedal feedback. My completely personal opinion is this: Anti-squat (no energy loss uphill) has slightly higher priority, because it improves the kinematic response characteristics (better downhill characteristics) at the same time. Actually, in practice modern kinematics with these priorities show only very minimal pedal feedback. Can you give a few hints for a long and problemfree lifetime of a suspension bike? First of all you need sound bearings for the rear section, but you should also take care to avoid common mistakes: Steam cleaning should never be used to clean anything but the tires, if at all. Never steam clean bearings or drive train components! Apart from that, STEVENS rear sections are built with proven technology, and in case service really is necessary, parts can be repaired or replaced even after many years of use. Maintenance-free, doubly sealed rolling bearings as well as special bearings are used, each kind in the places where it’s the most appropriate.
