Morning!
I can see that the BB shell size is 73mm and that the seat post clamp needs to have a 34.9mm band but I'd like to use an old but, in good nick, Octalink crank set so does anyone know what width (or length) the BB should be, also I can't see find out whether the front derailleur needs to be a high model or just normal (i.e. M760 or 770)… Any help would be appreciated.
Cheers
Front mech depends on the year and material of the Epic. The carbon ones require conventional (high clamp) ones, as the frame tapers near the b/b shell, whilst later metal ones require top swing (low clamp) to clear the gusset on the front of the seat tube, earlier ones you can use either IIRC, I'd say top swing would be a safer bet.
Bottom bracket size is a function of your chainset. XTs are 113mm on most frames, LX are longer, often 118mm, but you need to check for your exact chainset.
Edit: I need to read posts, it's a 2007, if it's an alu Epic you need a top swing, carbon is conventional.
