    I NEED HELP! BB Question

    Hello,

    I am brand new to mountain biking. Ive been road biking for a while and want something different.

    I have a 2008 trek 3700 The Crankset is shot. I have a Profile design Alpine Pro crankset I want to install. I know it needs a V2 splined octalink BB. Does anyone know the size? I have no idea.

    If you know, or better yet have a link to one for sale, Let me know!!

    Thank you!!

    Mike
