240 DEG 90 DF XD Slim Super Boost Rear Hub

DT Swiss 240 DEG 90 DF XD Slim Super Boost Rear Hub is a high-engagement rear hub built for riders who want faster pickup under power and the durability of a ratchet-style drive. The DEG freehub system uses simultaneous full-ratchet engagement to spread load across a larger contact patch than typical pawl designs, helping improve long-term reliability while delivering a more immediate feel at the pedals.

Tuned for modern trail and e-bike demands, DF (Degrees of Freedom) adjustability lets the rider choose how the hub behaves under suspension movement and impacts—without tools—so the bike can be set up for reduced pedal kickback and a smoother ride feel across changing terrain.

5 performance advantages for precise, durable power transfer

1. 90 Points of Engagement - Reduces crank “dead zone” for quicker acceleration and more controlled ratcheting through technical sections
2. DEG Full-Ratchet Drive - Simultaneous ratchet engagement distributes torque more evenly than pawl systems for balanced loading and reliability
3. DF Adjustability (0°, 10°, 20°) - Tool-free setup options to tune ride characteristics and manage pedal kickback behavior across different bikes or terrain
4. Low-Maintenance Architecture - Ratchet-based engagement is designed for straightforward servicing and consistent engagement feel over time
5. XD Freehub Compatibility - Direct fit for SRAM XD cassettes, supporting modern wide-range drivetrain builds

Approved for e-bike use up to 32 km/h or 250W (per DT Swiss specification).
