[fragledoozer]

out riding late last night and rear derailleur has come of, gona look at this morning in the light it looks like it has come loose and unthreaded anyone else had this???

Just put it back on. I wouldn't think it is a common issue.

I’ve never heard of that happening before. My guess is that it was never torqued properly and just worked itself loose. Is it still attached to the derailleur hangar or just floating with the hangar bolt missing?

messed the thread up needs a new rear hanger rear bolt still in derailleur bizarrely i had stopped to sort out my lights and it fell of if i had been moving it would of done more damage. I thought maybe my weight and size put more pressure on it i am big guy lol. Local specialized dealer have it now fixing it for me

Yep found that mine was half unthreaded after the last ride, fortunately I was checking the shifting and found the problem! No idea how long it had been working loose! Just retightened it and made note to check bolts more regularly!!!

This should be part of a regular bolt check on a bike, any bike, should get this, atleast every few rides, just as you oil the chain, take 10minutes, torque all the bolts and you will never have this happen.

Check if the threads are all fine on the mech hanger, if they look a little rough, get a new mech hanger as you will do more damage when it rips off.

Had this happen on my 2021 LEVO last night. Couldn't believe what I saw. Was riding with a buddy who was on a 2020 LEVO. After I got mine back on, he went over and checked his. Sure enough, his was a few turns from falling off as well.

Been riding mountain bikes for a loooooonnnng time. This is a first. I think it is a LEVO thing. Gonna put some blue Loctite on and give it another go.
