Safety from optimal chassis tuning! The progressive winding of the fork springs provides ideal functionality for road and racing use. With a short compression path they offer the highest level of comfort as a result of the finest response characteristics (low breakout force). With further compression the springs provide tight, precise handling for great traction and bottoming-out reserves. The recommended Wilbers fork oil should be used to correctly adjust the damper to match the fork springs - the viscosity may differ from the original oil.
