My rear maxle keeps undoing itself, it did it four times on two laps of Llandegla on saturday, am I doing something wrong or is it broken. Its on a 2013 Whyte T129s only a few months old ?

is it tight when you close the QR lever? Have you adjusted the allen bolt that’s within the QR lever?

As above, tighten the small allen bolt a few clicks inside the end of the lever.

It seems very tight when I close it, I wouldn’t imagine it would need to be tighter. Its also been ok up to now and all of a sudden since the wheels have been off its started playing up..
