These little anodized puppies are pretty straightforward. They convert the rear hub of the Sun Ringle Charger Pro wheelset to accept a 12mm thru axle system instead of a traditional quick release.
The adapters look fine, but the tool to hold the axle while you remove the preintsalled QR drive side adapter is not included. I tried using an allen wrench the same size as the slot in the axle and it started damaging the slot so I gave up until I have the tool. I would give them 5 stars if the tool was provided.
They are adapters and they work . Nuff said
