A dedicated rear hub for a dirt-jump build, with the simple, durable layout that suits pump-track laps and street riding. The 370 combines a 135mm threaded-axle interface with 32 J-bend spoke holes and a 6-bolt disc mount.
The single-speed driver uses a 12-tooth sprocket, with a 36-tooth Ratchet LN mechanism inside. That gives the bike a clear, straightforward drivetrain and keeps routine freehub servicing accessible.
