lee@trials Posted September 6, 2006 Report Share Posted September 6, 2006 Hey all, Not been online for a while... Seems like ages since I've even sat down at my pc. Anyway I'll get to the point. Today I purchased a FSA Alpha Drive B MTB Crankset (isis). I got home to find I have a square tapered (jis) bottom bracket.... Also the screws with this new crankset are much fatter than my old ones so before I go ahead and buy a new bottom bracket. Just wondering if all Isis brackets have the same size screw thread in them? Any help would be appreciated, -Lee (And yes it was incredible stupid to buy a crankset with out checking my bottom bracket first..... I learned that the hard way.... ) Quote Link to comment Share on other sites More sharing options...
bob87 Posted September 6, 2006 Report Share Posted September 6, 2006 No there are three sizes M12, M14 and M15Usually though most Isis bottom brackets are M15 size, just ask before you buy the BB.You might even get some with the BB. Quote Link to comment Share on other sites More sharing options...
JT! Posted September 6, 2006 Report Share Posted September 6, 2006 (edited) I've got a 113mm truvative gigapipe BB that you can have for next to nothing, also have the bolts with it so there's no problems there. The only thing i haven't got is the spacer to make it 73mm ccompatible, but you can pick that up from anywhere.I'd seem like i'd solve your problems. Edited September 6, 2006 by JT!
