So what broke, the hanger or a bolt?
And which bolt.
But I would replace any broken bolt - only a matter of time before it ends in tears.

For the sake of a few pounds now I'd rather change it than have to replace it, the mech, and rear wheel when it finally decides to let go.

What CD says.

If it is the hanger bolt, that does nothing until you remove the wheel, then you'll wish you had a working one.

thanks a lot for quick reply.its the bolt which attaches the hanger to frame and i guess thats true if i remove the wheel then its gonna be a problem.but the bolt head came off and the remaining of it is still screwed through the hanger and frame.how can i sort that out? now i can not remove the hanger.

Drill it carefully. It's made of not very stern stuff.

Is it a hex bolt or a chainwheel type bolt?

It's a chain ring bolt, same thing though innit - just an M8 bolt.

It doesn't do anything other than stop the mech falling off when you take the wheel out but I'd still replace it, shouldn't be difficult to remove, unless you've made a proper mess you should just be able to jam a torx piece in there and twist it out, shouldn't need drilling.

yes great cooldad its exactly like the picture.so its a chain ring kind of bolt and when i remove the wheel im supposed to undo the female part using a flat screw driver and itll come off.and next im going to have to find same installation bolts not a hanger itself.am i right? honestly i wish i could get the whole original parts asap but i have to wait for couple of weeks .any alternatives? thanks again.

If I am reading your post correctly and the bolt is snapped then the mech hanger should fall off when you remove the wheel as all that is holding it in place is the axle.

I bought a new hanger pre emptively and still in my camelbak and it came with a new bolt.

Was about £10 from JE James cycles, postage is free if you spend over £15.

This way you'll get a new bolt and a spare mech hanger and if you break the new mech hanger just use the new bolt on the original hanger.
