Thanks,
Yeah. I've already been talking with them. They don't have one that will work.
The big issue is that this is a Hexlock axle, there are no threads. It's basically a 12mm road version of the 15mm Manitou mtn bike axle. It's great for for getting wheels on/off quickly but apparently not so great for putting on an indoor trainer which is very surprising.
Anyone else have a C60 disc out there that have run into this?
