Well I'd discovered a while ago that pretty much all the trails they've been putting in around my I can ride in the middle chainring (till I'm knackered anyway). Which is good, but then I've always tried not to cross chain too much.
Now I was having an issue with my Xizang, it was having a fit in the lower gears, right when you needed them, figured it was a cross chaining thing, wasn't an issue in the small ring... till the other day, was all bad. Got it home on the stand, all messed up, couldn't figure it out.
I had had a big crash a while ago where the bike and I went down drive side, figured then that its a bent flismy XTR mech...or bent hanger, ouch. Then I realised the reson I went down was the issue deciding to jump the cogs when I was trying to climb a rock...
Decided to put another wheel it, took the disc whell off my Zaskar, not the same issue, the original wheel, it was skipping in only the 2nd biggest cog, but when you tried to adjust, everything went out of wack. New wheel was fine till it got to the biggest cog (both 9speed)...argh, different issue.

Thought today, lets have another look before handingto the bike store... figure it's either the cog, the mech, the hanger or the muppet trying to figure it out... letsjust figure it out... cassette was a 32...the other wheel...surprise to me a 34. Ok diving into the parts bin, pull out an old box with an well used cassette, 32...whip it on... no issues...
careful look at the cogs, slight bend in the 2nd cog... yay, well ...yay. No bent hanger, no $300 mech, just need a new cassette, too bad the bent one is relatively new.
 
Re:

Yeah.... i coukd have written all of that in 4 words.

Bent sprocket, that most unusual. Some early cassettes are take apartable, if yours is, then you could straigthten it.
 
Re:

Bend it back and use as a spare. Smaller cogs should be fine to use in place of the older more worn ones you've fitted.

M770? or older M760?

its probably quite difficult to gain purchase on the sprocket but one way may be to use two thick pieces of steel held in a vice on both sides of the sprocket then apply hammer. worth a try before binning it.
 
Re:

They're quite flexy and thin. I was thinking wide bladed screwdriver coming in from the back underneath. Depends where the bend is though.
