When all that matters is getting to the finish line as quickly and efficiently as possible we ride with the RockShox SID SL Ultimate TwistLoc 29in Boost Fork. This ultra-light cross-country-specific fork can mount a TwistLock system that quickly locks and unlocks our suspension on race day. The ultralight package comes with 100mm of travel supported by the proven Charger Race Day damper and DebonAir air spring.
