Hey guys,

I have a cervelo PX sram build. I noticed that the rear thru axle is 12x170mm ... everything I see from wahoo supports 12x 142mm and 12x 148mm.

I imagine all the cervelo P3Xs have the same rear thru axle.

Is there a special a spacer I need or am I crazy and everything's fine? (I don't think it would be fine)

Also.. I know I'd have to buy the xdr hub.

Looking for a sanity check.. and a plee for some sort of standard.
