I'm trying to install some Hollowtech II LX cranks on my '06 XC Pro frame. First off, is it a 68 or 73 mm BB shell? I tried measuring but it seems to come out a little wider than 68 but not quite 73. Anyways the cranks come with three 2.5mm spacers and I'm wondering how many I need on each side to make sure my chain lines up right and everything. Should I have 2 on drive side and one on non-drive? Or some other combination?
P.S. almost done building it up, just need to cable up the deralliurs, get longer tubing for my rear disc (XL frame), and put on a handlebar when it comes in the mail. I'll post pics when it's all done.
