Unanswered Question

This is a clarification, not a question, for anyone with a a Cycleops direct-mount trainer (e.g. Cycleops Hammer or H2 trainer). Cycleops direct-mount trainer may be adapted to bikes with different rear wheel spacings by the usage of the appropriate end caps, and the thru-axle adapter is NOT needed (nor is it compatible with the direct-mount trainers).
I mistakenly purchased this adapter, believing that it was needed to retrofit the Hammer trainer I bought (from Competitive Cyclist) to fit a disc-brake road bike, and it became immediately apparent when I took off the end caps on the trainer for 130 mm spaced bikes that what I needed were different end caps, as opposed to a thru-axle adapter.

No Problems Here

Does its job and does it well. Has allowed me to keep in bike shape during some of the more unfortunate circumstances of Utah weather.

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.
