240 DEG 90 DF XD Boost Rear Hub

The DT Swiss 240 DEG 90 DF XD Boost Rear Hub is a high-engagement MTB rear hub built for riders who want faster pickup under power and the long-term durability of DT Swiss’ ratchet-style drive. The DEG (ratchet) freehub delivers precise, consistent engagement with a broad contact area that distributes load more evenly than typical pawl systems, helping support reliability under hard accelerations and technical climbing.

5 performance-driven reasons this hub stands out for trail and enduro builds

1. 90 Points of Engagement - Shorter dead spot at the pedals for quicker power transfer when ratcheting through rocks, roots, and slow-speed switchbacks
2. DEG Full-Ratchet Drive - Simultaneous ratchet engagement creates a large contact patch for balanced load distribution and dependable engagement feel
3. DEG DF (Degrees of Freedom) Tuning - Tool-free selection of 0° / 10° / 20° settings to fine-tune ride characteristics, including reduced pedal kickback where suspension dynamics make it noticeable
4. XD Driver + Boost Rear Spacing - Built around XD cassette compatibility and modern Boost rear hub standards for current MTB drivetrains and frames
5. E-Bike Approved (Up to 32 km/h or 250W) - Rated for use on compliant e-bikes, adding confidence for higher-torque applications within the stated limits
