Tackle the peaks and charge descents, the RockShox SID Ultimate 3P FS-SID-ULT3-D1 sets itself apart from conventional XC forks. Now lighter than before and equipped with a robust 35mm chassis, it ensures precision and control at the limits of your ride. The advanced Race Day 2 damper introduces a three-position (3P) compression adjuster—offering a firm Lock for efficiency, a smooth Open for comfort on rough descents, and an effective Pedal mode for mixed terrain—all readily accessible to suit your needs. With its adaptability to intense cross-country sprints and adventurous backcountry rides alike, SID benefits from a new, higher-volume DebonAir+ spring, which provides a plush initial feel and extensive customization options to fine-tune your ride experience.
