I finally had to change the drive train on my Giant FCR2. It was a square taper BB but with the lack of choice around I knew I'd have to change.
I boughthttp://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=250703709910&ssPageName=STRK:MEWNX:ITon ebay and with CRC selling a BB for only £5 http://www.chainreactioncycles.com/Models.aspx?ModelID=34653 :P

Now that I've got these the splines on the crank are slightly too large to engage in the BB :x
Have I bought a dud on ebay or is the BB Mountain bike specific and I have to get http://www.chainreactioncycles.com/Models.aspx?ModelID=906 :x

    Note that chain reaction says:

    Splined bottom bracket for use with Shimano Octalink chainsets.

    Features:
    V2 MTB compatible
    Oversize BB spindle - large 22mm diameter hollow cold forged chrome-moly pipe billet spindle reduces weight, increases strength and rigidity
    • Octalink splined axle/crank arm interface - results in more rigid crank assembly compared to square tapered spindle
    • Sealed cartridge assembly with oversize ball bearings - maintenance-free high efficiency rubber seals keep out dirt, mud, and water
    • Cartridge design allows easy installation without adjustment
    • Shell Width - 68mm or 73mm
    • Spindle Length - 118mm or 126mm


    Which means you probably went and bought the wrong bottom bracket, and yes you will have to buy the other bottom bracket you linked.
