Compatibility and Mounting
The hub side screws into an M12 × 1.25 threaded hole. The wheel side is secured with an M12 × 1.25 nut, whose flange width must match that of the rim.
Check the available depth in the hub, the rim thickness, and the nut engagement. The 52-mm dimension (C) includes the end slide rail: it does not correspond to the fully threaded length.
