- Q & A
Works but missing spacers
- Familiarity: I've used it several times
This thru axle adaptor works well so you can put your thru axle equipped bike onto a trainer. I ordered the 142mm axle and it was to be missing spacers so there is a large gap between my frame and the end of axle that contacts the trainer. If you have a Cycleops trainer and have a thru axle on your bike, this will allow you to mount your bike and train indoors.
