DT Swiss Ratchet EXP MTB Hub Driver – 12×142/148mm Boost Compatible

The Ratchet EXP Freehub Bodies are engineered for riders seeking precision and durability in their mountain bike setups. Designed with a sleek matte finish, these lightweight aluminum components offer a modern aesthetic while prioritizing performance on rugged trails and technical terrain. Available in two distinct configurations—ceramic bearings for the 180 model and steel bearings for the 240 variant—these freehub bodies cater to different riding styles and demands. The 180 version delivers ultra-smooth engagement and minimal friction for speed-hungry cyclists tackling high-mileage epics or fast-paced descents, while the 240’s steel bearings provide unmatched durability for aggressive riders who prioritize reliability under heavy loads or extreme conditions.

One standout feature is the open design of the freehub body itself, which eliminates the need for additional seals by relying on the hub shell’s integrated protection. This approach reduces weight without compromising on water resistance or debris management, making it ideal for cross-country racers and trail riders who prefer low-maintenance hubs that still handle muddy or dusty environments effectively. Compatible with SRAM XD 11/12-speed cassettes, these bodies ensure seamless gear shifts and consistent power transfer across varied terrains.

Built for modern bikes, they’re designed to work with 12mm thru-axle systems and support both 142mm and 148mm rear hub spacing—perfect for pairing with popular 27.5” or 29” wheel setups in enduro or all-mountain builds. Whether you’re chasing speed on fire roads or navigating steep climbs during multi-day adventures, the Ratchet EXP Freehub Bodies deliver responsive performance tailored to your ride’s intensity level.
