I am in the process of getting a replacement frame and wondered if anyone can tell me about bottom bracket compatability. I intend to put all my current equipment all onto a new frame and wondered if the bottom bracket is specific to my crank set or to my frame. I am making sure that seat post , steerer tube , dropout , and BB thread size are all ok but cant seem to find out if my new frame will want a different length of BB or wether it is particular to my crank set. Any help would be much appreciated. Nick
