Fixing a bent mech. hanger ;-(

Zardoz said:

Just repaired my bike (faulty shifters) lovely ride etc
etc but two miles from home I managed to throw the rear
mech into the spokes.

I've taken the chain and the mech off and most of the
damage seems to be with the hanger (it's a Peugeot frame,
alloy tubing), twisted and bent inwards. I've bent it back
a little way with mole grips. Anyone got any good tips to
true it up? I've got access to a workshop if I need to
make a jig... but it might be easier to try my trusty LBS.

Nice evening ride though :-) And I've got my MTB for
tomorrow :-))

Park Tools do a device for checking the alignement, would be
easy to copy IMHO, check out their website.

Copyright? They may have spent a lot of devlopment time
on the jig?

Is it a sacrificial replaceable hanger, or just part of
the frame? If the former, get a new one and breathe a sigh
of relief. If the latter, you're probably in for grief.
Alu frames don't like being bent.

I agree with Simon - you'll need to be careful if it's an
integral aluminium hanger.

If you feel that you can straighten it, it's possible that I
may be able to help you, because I have one of the Park
tools to which someone else has

both ways, unfortunately, because it's heavy - I suspect
that the LBS repair would be cheaper. Let me know if I can
help; I obviously don't want anything for its use.

Thanks for the offer. It's a Reynolds alloy which is some
sort of steel (and there's not a replacable dropout).

I'll drop it in the LBS and have them sort it out.

More work with the mole grips could possibly sort it but it
would indeed be more sensible to leave it to the LBS if you
can't easily get the angle correct.
