Hi

Please could I ask for some advise regarding upgrades to an ageing 2008 GT Avalanche 1.0
http://www.evanscycles.com/products/gt/avalanche-10-disc-2008-mountain-bike-ec000669#features

I need to replace most of the drivetrain and as money is tight I'm looking at sourcing and fitting the components myself (will probably be posting again when it's all gone wrong). Anyway, before I flash the cash, does anyone know if I'm likely to run into any incompatibilities or issues with the following:

Shimano Deore M592 Shadow 9 Speed Rear Mech - http://www.chainreactioncycles.com/shimano-deore-m592-shadow-9-speed-rear-mech/rp-prod40542
Shimano Deore M590 9 Speed Triple Chainset - http://www.chainreactioncycles.com/shimano-deore-m590-9-speed-triple-chainset/rp-prod40496
Shimano Deore HG61 9 Speed MTB Cassette - http://www.chainreactioncycles.com/shimano-deore-hg61-9-speed-mtb-cassette/rp-prod31059
SRAM PC951 9 Speed Chain - http://www.chainreactioncycles.com/sram-pc951-9-speed-chain/rp-prod9911

I need to swap out the bottom bracket too, but I don't know what size until I get the old out. All I know is it's octalink cartridge sealed.

Any advise or recommendations for alternative set up would be much appreciated.

Dan

    BB size does not matter as you are going external just read the manual.

    you will also need to get the BB shell faced.

    presuming your shifter is also 9spd there are no issues.

    If money is tight, get good used parts not new and save a fortune....

    Thanks, yes shifter is 9spd. Regarding the BB, I don't have the manual and can't find a copy online. Will start searching on BB replacement and 'shell facing'.

    Good tip, but I think I'd rather go new for piece of mind. Thanks

    You don't need the manual. Just read the manual with the new cranks. It doesn't matter what's currently in there.

    Cheers, just been looking more at the crankset - there's a hollowteck bb included in the set.

    Yes we know, we've been trying to tell you that! And it's Hollowtech2...Hollowtech is different.

    Just about my whole bike has been bought used and it all has worked perfectly well, in fact more reliable than some of my mates all new stuff!

    That looks a fantastic offer, but as my front mech and shifters are still ok, I'll buy the bits separately over the next couple of months to keep costs down and spread the outlay.
