Zero skis<br />
The new Zero skis might be an ideal alternative<br />
on falling or new fallen snow close to 0°C.<br />
All major ski brands now carry such models. They<br />
have a special rubber/polymer blend material in<br />
the kick zone, which to a certain degree can be<br />
manipulated by sanding paper. The grit# to use<br />
is determined by track and snow conditions. Most<br />
common are #60 to #100.<br />
General tip<br />
With precipitation a combination of #80 and<br />
#100 is satisfactory. These conditions are characterized<br />
by a continuously supply of moist snow,<br />
never creating very hard or glossy trails.<br />
With shiny tracks a more coarse paper might<br />
be used such as #60 and #80.<br />
Remember that Zero skis are not always the<br />
solution for difficult conditions. During long lasting<br />
competitions or tracks having large altitude<br />
differences, conditions might alternate or change.<br />
In such cases, the alternatives of using traditional<br />
wax, might work better.<br />
PROCEDURE FOR RUBBING<br />
1.<br />
Set the marks for the kick zone, about the same<br />
length as for soft kick waxes.<br />
2.<br />
Roll the sanding paper around a waxing cork to<br />
get a stable surface for working.<br />
3.<br />
Sand the kick zone by working at a 45 degree<br />
angle, towards the running direction along the<br />
kick zone. Repeat the process from the other side,<br />
thus creating an arrow pattern towards speed<br />
direction.<br />
4.<br />
Remove dust and debris with Fiberlene (T150) or<br />
similar.<br />
5.<br />
You can now repeat point 2-4 using a finer grit#<br />
paper. Two different grits are often used, but<br />
always start with the more coarse one.<br />
6.<br />
Lastly, treat the base with Zero spray (N0002).<br />
Keep the bottle 4-5 cm from the base, spray on<br />
both sides of the groove (4-5 sec. on each side).<br />
Let the skis dry for 2-3 minutes before use. It is<br />
also possible to work in Cera F powder (FC8X) by<br />
hand to the rubbed kick zone.<br />

The kick zone will always collect dirt. Cleaning<br />
with a wax remover (I64 or I74) is recommended.<br />
Let the ski dry for 30 minutes.<br />
