Chain 'slipping' under tension and when generally riding

Afternoon all,
I've got an ongoing problem where my chain 'slips'.
Initially it was under load from the crank. I first thought it was due to a worn middle chain ring so I replaced it; Didn't solve the problem.
Then thought it might the chain; Replaced it last night and, whilst the old one was stretched beyond belief, this hasn't helped either.
I did however re-index and set-up the rear derailleur in this time and the 'slipping' is not coming from this area.
I've just order a couple of new jockey wheels thinking that this might solve the problem but if it doesn't... Whats next!?! RE-index and set-up the rear derailleur and hope that it solves the problem?
Cheers,

Did you replace the cassette? If your chain was well stretched then cassette is the first thing to change0

I haven't as yet no; I'll be honest and say I'm hoping its the smaller things than larger
Will add that to the list... Thanks,0 -
That's your problem. You must replace together when the chain's done damage0

As the chain streteches, instead of having the rollers engage with all the teeth on the cassette available (about half the teeth) it only engages with the last one at the top in turn, this increased load wears the teeth to match to the new chain pitch, replace the chain only and you go back to one tooth only and it jumps.Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0

Learn something new every day. Thanks for the advise guys.
Any advice on if there is a great difference between these two options:-

http://www.chainreactioncycles.com/shim ... -prod31059
Bike is only used for road riding but i'm looking at changing to a road bike next spring so trying to keep costs down without compromising ride-ability over the winter.
In addition is there anything else that would be prudent to buy/replace at the same time? Or specialist tools that would be required?
Cheers for your help.0 -
The HG61 is lighter and the one I'd go for as it's only a few quid more.
You need a cassette tool and chain whip to change it.0 -

Thanks; My only concern with the HG61 is that on Wiggle its listed as a 29er cassette; That said it could just be that they have a different variant...
Another couple of tools to add to the tray; Wouldn't be getting far without them though so thanks for the help

The HG61 you link to is not on Wiggle.
Just pick your ratio - like for like is best if you're not sure (count them!) - 11-32 or 11-34 are the main standards0 -

No i know; Wiggle one says 29er, CR one linked doesn't so hoping its different!
Thats tonights fun task... That or buy blind and have an easier/harder first sprocket depending on if I guess right 0 -

How long does it take you to count to 32? It's more of a 20 second task!
The Wiggle 29er thing is in response to the 12-36 HG61, which was designed for 29ers, as the bigger wheels have the effect of increasing the gearing, so they did a lower range cassette. Obviously nothing stopping you using it on any size wheels, but it's a narrower range than 11-34, so pretty pointless.0 -
Well the good news is (thought this was long overdue an update) it all worked out fine
New Cassette, new chain, good as new bike
Been bitten by the bug now its all working fine and i'm enjoying riding so now looking at a road bike in the spring 0 -

Should probably have expanded on that statement I'm riding roads on a MTB; Using country rock tyres and decided the other week that i'm going to try getting in shape for a triathlon next year... 0
