Servicing my 07 Stumpy
Discussion
Was having probs with gear jumping, chain 'grabbing', gear slipping etc...
So changed my chain and it got worse !
So ran out of time to work on the bike, but found a local chap who works from his house. My bike is XT/XTR stuff - he changed all 3 front rings, a shifter cable, replaced the front n back pads on the Avid J 7s, replaced the rear cassette etc (whilst encouraging me to resist, for example, changing all 3 rings), He also picked up and returned the bike plus tested it on a decent up hill climb. Anway he charged me £153 all in. That was about £100 less than I thought it might be. So am chuffed with that!

Tip for the top:
Your chain wears out as you use it.
Let it get too far and the cassette & chainrings wear to compensate for the worn chain.
Change the chain now and it won't run properly on the rest of the worn drivetrain, meaning you end up having to change the lot.
The solution? Invest a couple of quid in a chain measuring tool and change the chain as soon as it stretches by 1%.
That way the cassette will last a bit longer (maybe up to 3 chain replacements) and the chainrings will probably last a lot longer.

Funny you chaps mention all this. I had a similar situation that left my '06 Stumpy in a mess:

My worn out chain snapped and I ended up changing two front chain rings, the chain, cassette, and fitting a new XT front mech (as mine had been belt and then re-bent back into shape a couple of times).
I also fitted some XT shifters and what a difference all the parts made!
I did an alpine tour over the weekend and it was fantastic having the bike slip into gear exactly when I needed it to, even under a little pedal pressure.

It was great to have my bike back in rude health. There is a very tricky steep climb with mud roots loose stone and sloppy rocks. Got up without a foot down and overtook some much younger guys who I came across, much to their amazement. A bike that is totally in tune makes all the difference.
