• I've just bought a Langster frame and need a bottom bracket and crankset, but the choice and properties of them are overwhelming. Chainline, spline length, Square taper, JLS, sealed, externalc cups - too much for me.

    All I want is someone to hold my hand and tell me it will be okay.
    Or alternatively please advise me on what is the de-facto choice for a lightish yet durable BB and CS suitable for a 2009 Langster. I'm looking for something easy to install and maintian that 'just works'.

    I like the look of the SRAM 300S courier. Anyone comment?

    Also what special tools will I need?

    Chars...
