DT Swiss 240 EXP Rear Hub | Ratchet EXP 36T | Road, Gravel & MTB

The 240 EXP rear hub pairs DT Swiss’ renowned 240 hub shell with the Ratchet EXP freewheel system, a simpler, lighter and even stiffer evolution of the famous Star Ratchet. It’s the hub many of the world’s best wheels are built around.

Available in road, gravel and MTB spacings with Shimano road, Shimano HG MTB, Microspline and SRAM XD freehub options.

Who is this for?

Custom wheel builds where reliability, low weight and serviceability matter.

Who is this not for?

Riders after a complete wheel – this is the hub only.

Why we love it

The Ratchet EXP system is ridiculously durable and easy to service. Freehub bodies can be swapped later if you change drivetrains.

Hot tip!

Not sure which axle, brake mount or hole count you need? Check your fork and frame axle spacing, your rotor type and your rim’s spoke count before choosing.
