Trouble shooting
We like to give a few examples which
are common in Road Racing and how
to solve them.

The front wheel ”chatters” entering
a corner, the problem goes away, as
soon as you let the brakes off, or
when you get on the power.

This is caused by the fact that the fork

reaches the progressive, hard part at
the end of the travel.
