The RockShox SID Ultimate Race Day 29 - 2P is a high-performance cross-country suspension fork built for riders who demand maximum speed, precision, and efficiency on modern XC courses. Designed around 29-inch wheels, it delivers a supple yet supportive feel that keeps your front wheel glued to the ground over roots, rocks, and rough race tracks, while still offering the snappy acceleration and low weight that competitive riders expect. The SID platform is known for its excellent small-bump sensitivity, predictable mid-stroke support, and controlled end-stroke ramp, helping you maintain traction and control without sacrificing pedaling efficiency.
Equipped with RockShox’s Race Day damper, the SID Ultimate focuses on fast adjustments and minimal weight, giving racers a clean, simple interface to fine-tune performance for changing course conditions. The 2P (two-position) remote or crown-adjustable lockout allows you to quickly switch between an open, fully active mode for technical descents and a firm mode for sprints, climbs, and smooth sections. With a stiff chassis optimized for precise steering and modern XC geometry, this fork is an ideal upgrade for serious racers and performance-focused riders looking to sharpen their bike’s handling and unlock every bit of speed on race day.
