High-end hub for fast road bikes and wheel builds.

The DT Swiss 180 Straightpull Ceramic rear hub with a 130 mm installation width and 5 mm quick release is the premium foundation for lightweight, stiff wheels on road, gravel, or aero bikes with rim brakes. Thanks to Ratchet EXP 36 and SINC ceramic bearings, it combines extremely low rolling resistance with direct power transfer - ideal for ambitious riders, time trialists, and high-quality custom builds.

The redesigned Ratchet EXP 36 toothed-disc freehub reduces the number of components, increases bearing spacing, and makes the hub lighter, stiffer, and even more reliable. All teeth on the toothed discs engage across their full surface, creating a robust system with defined, direct power transmission. Maintenance and conversion are particularly easy thanks to the no-tool concept: end caps and the freehub body can be removed without tools.

This version comes with an SRAM XDR Road freehub body and is therefore perfect for modern 12-speed SRAM road cassettes (XDR). The Straightpull design with 24 spoke holes ensures high lateral stiffness and even tension distribution - ideal for stiff, lightweight performance wheels. At the same time, the hub is approved for use on e-bikes up to 32 km/h / 250 W.

Highlights:

• Ratchet EXP 36 freehub: direct engagement, high reliability, and reduced weight.
• SINC ceramic bearings: extremely smooth-running and durable for maximum speed.
• Straightpull construction: 24-hole hub for stiff, precise wheels.
• QR 130 mm & rim brake: ideal for classic road frames and aero bikes without disc brakes.
