G'day!
Hope someone can help with my annoying xtr problem...
I've got a Cannondale F800, with XTR drivetrain - decent weight and generally a smashing bike. However, recently the chain has started to fall off between the cassette and wheel - usually when applying maximum power which means it wedges in good and proper.
I've adjusted the stop screw as far as it will go - in both directions to be sure - and it makes no difference. Strangely, it only does this for the first mile or so then settles down. Gear changing is fine otherwise, and it's OK if I leave it on the 2nd cog.
Is it possible the mech's twisted? I recently replaced the rear hanger after hitting an errant log looking for new trails, but the mech looks fine...
BTW I normally ride at Hopton Woods in Shropshire. Some good new singletrack has been made there by those fine chaps at Pearces.
Did you adjust the top or bottom screw
I did both after the one marked L made no difference...

1, Try to get the hanger alignment checked first.
CRC do tools, which I have, but are expensive.

2, If that is good, the mech can still be bent after your crunch.
Trying a new mech is the simplest way.
I had an XT M750 that got bent and was erratic, but did not appear damaged. The mounting bolt and its surround was off-square, so scrap.
You are welcome to bring your bike round and I will help you check the hanger, but I live in Wokingham.

Thanks for the offer, but Wokingham is a long way from Shropshire!
I spose, being quite an old mech, it's worth just replacing it.
In which case, is it weight weeny XTR at £125 (!), 2oz more XT or X0 carbon? Christmas is coming so maybe Santa might be persuaded...
You probably already know this, but you can't just put an X0 mech on there without changing the shifter to SRAM as well. Also you say your mech is old so I'm assuming 8 or 9 speed - you can't use a new XTR 10 speed mech if that's the case, you need a 9 speed one as the cable pull is different.
I don't think I'm willing to pay X0 prices anyway... £84.95 is the cheapest I've seen a 9 speed XTR rear mech.
