Wasn't sure the 12mm thru axle would work with my trailer setup, but this adapter threaded in cleanly and the hitch feels rock solid on bumpy pavement. Took maybe five minutes to install.

Olivia ★★★★★ Sep 11, 2026

The 217mm length lined up perfectly with my Maxle rear axle, and the trailer hitch clicked in without any wobble on the first ride. Took maybe two minutes to swap in with a hex key, way easier than I expected for a thru axle adapter.

Was nervous the M12 x 1.0 threading wouldn't match my rear axle but it screwed in perfectly, no wobble at all. Trailer feels solidly attached even on bumpy pavement.
