Original second-generation Sachs coaster-brake rear hub with a die-cast zinc housing, compatible with Swiss mopeds equipped with Sachs 504 HG engines and 17-inch rims.
If the sprocket is replaced, the hub can also be used on Puch X30 Sport models.
The 50-tooth sprocket is riveted and can be replaced.
The coaster brake hub is shipped without a brake anchor plate. The wheel axle, including all internal components, is included.
Note: New coaster hubs must be installed by a qualified technician in accordance with the relevant factory documentation. Bearing play must be checked after installing the brake anchor plate and readjusted if necessary. You’ll find our tutorial on this below. Improper handling and any resulting damage do not constitute grounds for a warranty claim.
Additional hub bodies, an alternative sprocket, and matching screws, as well as a brake pad and maintenance kits, can be found in the accessories section.
