This product combines my SC2 shaft mount part and a Drivelock for the 22mm shaft of the Midge motor.

The drive lock will clamp very firmly onto the shaft and the adapter.

My adapter then gives you 6 x 70mm threaded holes to attach a wheel or QR. There are also 3 threaded holes for the SC2 QR system if you want to use that system.

This product provides a really strong connection to the shaft.
