These spacers allow a thru axle frame, 142 x 12, to fit to the direct drive trainer. A quick release skewer secures the bike to the trainer.

A machinist fabricated these spacers to allow for a mountain bike to fit to the trainer. I have been using this setup for the past few months and it works very well.

If anyone is interested in something like this, we can make a small batch and sell them. Payment would most likely be paypal.
