The DT Swiss 350 MTB rear hub is the trusted choice for riders who want proven performance without unnecessary complexity. Built around DT Swiss's Ratchet System, it delivers reliable engagement and straightforward servicing — exactly what you need when you're away from the workshop.
- Ratchet System 36 SL for direct, crisp power transfer on every pedal stroke
- Lightweight aluminium shell engineered for trail and all-mountain demands
- Freehub body can be swapped between Shimano HG, XD, and Micro Spline without special tools
- Designed for long-term serviceability — ratchet rings and bearings are user-replaceable
- Compatible with a wide range of axle standards to suit most modern MTB frames
The 350 series sits at the core of DT Swiss's hub range, prioritising reliability and longevity over minimal weight. Its two-ring ratchet mechanism has fewer parts than competing designs, making service intervals longer and in-field fixes more achievable. Whether you're building a workhorse trail wheel or replacing a worn hub on a trusted bike, the 350 MTB rear hub is a solid choice.
Compatible with most modern MTB rear dropout standards. Spoke hole count and axle specification vary by variant — verify before building.
