This is what BB the spec sheet says my bike has...
Truvativ Power Spline, cartridge bearing, 68 x 113mm for 47.5mm chainline

and these cranks
Truvativ ISO Flow 3.0 for Power Spline, replaceable rings

Im getting confused between ISIS, octalink and powerspline/Splined.

This may be a completely daft question (but I have never had to repalce a BB before)...Do i need to buy a powerspline BB because of the description of the cranks?
I want a decent new BB - would one like THIS work? If not can anyone point me in the direction of one that would so I can get my head round what Im looking for.
Cheers

    Is powerspline different to splined?

    Might have to be an upgrade of the cranks as well then!

    (thanks for quick reply)

    Powerspline is Powerspline.

    it is not ISIS splined it is NOT Octalink splined it is NOT 36 splined splined it is NOT 48 splined splined. it is also not Howitzer splined.

    ok thanks - wasnt sure if it was just each different manufacturers way of saying the same thing.
