I upgraded my rear-mech with a new cassette, chain and new cables a few weeks ago since then i've mangled two rear mechs!
Both times I've just been riding along; not in a big gear; not at the extremes of the cassette, the mech just seems to get caught on something (the chain?) and bends and snaps!
I've got to buy a 3rd mech and I'm wondering why it's happening, is it just bad luck?
The mech I replaced (an ageing XTR) I'd had for years without any miss-hap but now I've mangled two XT mechs, one was a Shadow and the one prior to that was a standard.
Any sugggestions?
