Rock Shox Bo XXer Ultimate Charger 3. 2 - 29" Boost(TM) Fork Maximum control and composure at the highest speeds The Rock Shox Bo XXer Ultimate Charger 3. 2 is built for one purpose: keep the bike's front end composed when the trail is doing everything it can to knock you off your line. The new Linear XL air spring has a coil-like ride feel, with a supple top end for traction, supportive through the mid-stroke for stability, and finished off with a jounce bottom-out bumper that keeps the last part of the travel controlled, not chaotic. Or, select the Debon Air+ air spring for a balance between buttery-smooth small bump absorption and a higher ride height with support throughout the fork's travel. Exclusive to Ultimate-level forks, Butter Wagon Tech continuously feeds oil to the bushings to cut friction and keep the fork moving freely across the full service interval. Pair that with Charger 3. 2 damping and Butter Cups technology to filter high-frequency chatter, and you get a new Rock Shox Bo XXer that stays quiet, predictable, and fast, exactly what you want when the clock is ticking.
