Discover unparalleled cross-country cycling performance with the RockShox SID Ultimate Race Day fork, a premium suspension component engineered for precision and speed. Crafted with a rigid 35mm chassis, this fork expertly balances lightweight design and exceptional stiffness, delivering responsive handling and enhanced control on demanding trails. Featuring the innovative Charger Race Day 2 damper, it offers dual compression settings—Open for fluid suspension movement and Lockout to optimise pedalling efficiency on flatter terrain. This combination ensures you maintain momentum and confidence across varied course profiles.
