To use for 'drive axles', in twin wheel format, simply install the TQ185a Spacer Ring onto the steer face, followed by the second wheel with the steer face inwards. The spacer rings have tiny recesses to locate with the spyder, thus keeping the inner & outer aligned. The tyre spacing is 4mm, this may be reduced if required by sanding the spacer ring thinner.

Drill the inner hub reduction face to mount the drive axle. Again the hub may be shortened before assembly to offer a narrower track if required.
