Cross-country purists… we see you. You’re why SID SL Ultimate is the lightest XC fork on the trail. But weight is meaningless without world-class performance and durability. SID SL features a new Charger Race Day 2 Damper with three-position (3P) compression damping—rigid Lock, plush Open, and efficient Pedal positions, on demand for every inch of the race course.


- Our lightest 32mm chassis ever. World Cup-proven performance, built for your next podium result.
- Longer-travel 110mm option, in case you’re feeling extra.
- Charger Race Day 2 damper is the lightest damper on the market. This 3P damper features three compression positions: Open, Pedal, or a rock-solid Lock.
- Machined crown for lighter weight and greater strength.
- Covetable “Blue Crush” signature colorway and Ultimate High Gloss Black, featuring the new lustrous Pearl White graphics package.
- Maxima Plush Dynamic Suspension Lube reduces friction, lasts longer, and enhances suspension performance ride after ride.
-DebonAir air spring is tuned specifically to meet the demands of XC and maintains a higher ride height for increased confidence and control.
