bob87 Posted November 15, 2006 Report Share Posted November 15, 2006 Hey guys I've now built up a 05 Pitbull and the BB i got doesn't fit that well.Its a standard size 118 Fsa Isis BB. I'm running Middleburn pro cranks, 22 tooth chainring.Well when i fitted it at first the chainring rubbed on the frame, so added a spacer to the drive side thinking this would be the problem sorted but no.Now i find that after being spaced on the right side the left hand crank arm now sits far to close to the frame, sometimes even clipping it on the way round.What i would like to know is what is the right BB width, and what sort you would recommend. I was looking at those SKF ones.Thanks. Quote Link to comment Share on other sites More sharing options...

Onza Kieron Posted November 18, 2006 Report Share Posted November 18, 2006 If you have the cash then SKF 600 bb, either lifetime or 10 year warrenty, so it will be the last one you buy (unless yours gets stolen or you need 2 for some homosexual reason) Quote Link to comment Share on other sites More sharing options...
