Restore the lightning-fast engagement and silk-smooth rolling performance of your premium mountain bike wheelset. The Syncros Silverton / Revelstoke 1.0 XD Hub Repair Kit is an authentic workshop-grade replacement package engineered specifically for high-end Syncros carbon wheels. Over seasons of intense trail riding, heavy downpours, and jet washing, internal hub components inevitably suffer from water ingress, grit contamination, and bearing degradation. This comprehensive overhaul kit provides everything required to refresh your rear hub's core internals in one single package.
Constructed from premium, high-strength aluminium alloys, this genuine replacement ensures perfect mechanical tolerances and seamless power transfer. The kit comes completely loaded with an authentic SRAM XD driver body, high-precision sealed cartridge bearings, a replacement internal hub axle, and matching drive-side and non-drive-side end caps. Tailored to fit the original factory-specified Centerlock hubs found on select Scott Spark and Genius models, this assembly eliminates sloppy cassette play, prevents ghost-shifting, and brings factory-fresh reliability back to your drivetrain.

When assembling your new XD freehub body, avoid using heavy, thick axle grease on the internal drive pawls and engagement teeth. Thick grease can easily become sticky in cold weather or attract fine trail dust, causing the internal springs to jam and stick, which leads to dangerous drivetrain slipping. Instead, apply a light coat of high-grade freehub oil or specialized, thin freehub grease to keep the engagement mechanism moving freely and snapping cleanly into place!
