M-WAVE Unisex - Adult BF Fixed Axle Mounting System for Bicycle Trailer > Single 40, Silver

Absolutely rubbish. Just two lumps of soft steel poorly machined. The wheel was getting loose constantly. This morning after a fortunate flat before a long descent I noticed that the threads were gone, I couldn't tight the wheel any more. Never thought a flat could potentially save me from an accident.

i have seen alot of negative comments about these types of bolts, however my experience is that they work well these didnt require me to take off my locking nuts which saved on over tightening the bolts causing them to thread.ive only used my trailer with these twice but can honestly say they work really well and have not caused me any issues happy with them so far, they do the job
