For those with a carbon Sirrus with thru axles who are looking at how to adapt it to a fork-mount bike rack set up for QR skewers, I can confirm that this thru axle adapter works perfectly and is $20 vs. the $60 that Thule and Yakima want for their equivalent products. I think the same model works for the new Diverge.

There is some concern about the axle bosses in the adapter being slightly too big to go into the fork on some 12x100 thru axle forks, but it works fine on the carbon Sirrus.
