I've tried to get my head around chainsets and bottom brackets without a great deal of success and i would like to upgrade my current set up. I am told by Specialized that my "Sirrus uses a 68mm English thread bottom bracket shell. This gives you a high degree of compatibility with aftermarket chainsets".
At the moment I have a Sram 3 piece, 10-speed, alloy chainset (48-34T). The BB is a (brand new) Truvativ Power Spline Bottom Bracket (68x108).
Any recommendations? Amazon are doing what seems a mega bargain 'Sram S950 Chainset GXP 50-34T GXP Cups Not Included' for under £70 at the moment and i'm very tempted, but have no idea whether it will suit the bike :-(
Thanks
