Wasn't sure the 172mm would line up with my frame but the thread caught perfectly on the first try. Trailer hooks up solid now, no wobble at the axle even on bumpy pavement.

Bolted this onto my Shimano 12mm rear axle in a few minutes and the trailer hitch lined up perfectly. The M12 x 1.5 threading screwed in clean with no cross-threading, which was my main worry. Solid little adapter, exactly what I needed to get the kids riding again.

Wasn't sure the 178mm would clear my rear dropout but it threaded in smooth and the trailer hitch sits tight now. Took maybe five minutes to swap and my kid's already begging for another ride.
