I am putting together a bike and have a question for you. What kind of Shimano octalink bottom bracket will fit my bike? I will keep on using octalink because I allready have XT crankarms and I'm on a budget. The crankhouse measure is 73mm. I will mount a chainguide from Blackspire it has to be installed toghether with the bb. I thought i could use my old bb, but the axle is to short. My old bb was 73mm/113mm.
Will a 73/118mm solve the problem, or do I have to buy a "e-type" bb?
