25 years after the original RS-1, the fork that revolutionized mountain biking, RockShox does it again. A chassis design never seen before, which integrates the fork's steerer tube, crown and legs into a single carbonmainframe. The all-new Accelerator Damper, which combines incredible small bump performance with an ultra-efficient lockout. And Predictive Steering, a reimagined interface between hub and dropouts which enabled us to create an inverted fork light enough for XC racing and stiff enough for trail riding.
Contrary to popular belief, rewriting the rulebook isn’t all upside. After designing the fork chassis from the ground up, it meant developing an all-new damper to eek every percent of performance out of the RS-1. A tall order, but one that RockShox fully embraced.
We started by reevaluating how XC athletes produce efficient power and navigate course conditions while fatigued. We created a firmer lockout for moments of maximum sprint efficiency. We added the Rapid Recovery system to keep the fork riding high, in the plushest part of the travel. Then air was eliminated from the damper circuit ensuring absolute consistency. The Dig Valve compression tune was created to manage diving during successive hits and heavy braking. We eliminated material redundancies by housing the circuit in a sealed cartridge, reducing weight. We even made the cartridge easily serviceable in the race pits or at your local shop. We believe the Accelerator Damper crystalizes the performance of RS-1 by helping riders turn every pedal stroke into acceleration towards the top step of the dais.
