My superstar BB has died and I'm thinking of taking the opportunity to upgrade. My bike is my only bike, so need to be good for all day XC and occasionally ragging down the Fort William runs.

Want double+bash. Is this a good idea? http://www.chainreactioncycles.com/Models.aspx?ModelID=27684 Any reason the Saint set will no work with a standard XTR mech from a few years ago?

Any other suggestions? Don't want to spend a fortune. Strength/durability preferable over weight.

Cheers!

Gareth
