The RockShox Zugstufe SID (B1) is a genuine RockShox rebound adjustment assembly designed specifically for SID forks of the B1 generation. As an original spare part, it restores precise rebound control so your fork can track the terrain smoothly and predictably. Over time, internal components can wear or get damaged, leading to inconsistent damping or limited adjustment range. Replacing the rebound unit with this RockShox component helps bring back the crisp, controlled feel that SID forks are known for on demanding XC and marathon trails.
This RockShox Zugstufe SID (B1) part is ideal for riders who want to maintain their suspension at factory performance rather than replacing the entire fork. It is intended to be installed as part of a proper service, following RockShox guidelines and using appropriate tools and suspension oil. Whether you are refreshing a race bike or extending the life of a trusted training fork, this rebound assembly offers a reliable, cost-effective way to keep your SID responsive, tunable, and ready for fast, technical riding.
