Why We Like The RockShox BoXXer Ultimate RC2 27.5in Boost Fork
The RockShox BoXXer Ultimate RC2 27.5in Boost Fork is built to be 100% race ready straight out of the box. The Charger 2 RC2 damper has been fine-tuned for unmatched rebound control and to handle big hits at high speeds. The ultra-responsive DebonAir DH air spring helps reduce the amount of fatigue we accumulate over the course of a long race day with its impeccable small bump sensitivity while also allowing the fork to ride higher in the travel for precision handling and support. Synonymous with podium-level performance, the BoXXer Ultimate is our fork of choice for our next downhill bike build.
