The Duck Posted September 23, 2007 Report Share Posted September 23, 2007 (edited) Running front freewheel by any chance?Edit: Sorry not very helpful... If so thats your problem, need to take some washers out or get a thinner bash etc. because external bbs aren't designed to be used with a front wheel set up. There just isn't enough space.

eskimo Posted September 23, 2007 Report Share Posted September 23, 2007 You can get a few different shell sizes. Most common is 68mm.Anyhow i hear of a few problems like this when it comes to using them. Best bet would be to, bodge a washer in there somewhere. Or just not worry to much about it?But you say it goes stiff when you put the crank arm on? Or isit when you screw the second cup in?

timmorley Posted September 23, 2007 Report Share Posted September 23, 2007 alright mate, the problem might be that your bb shell is not faced so the paint is uneven this would make your externall bb sit cok eyed in the threads putting strain on the bearing which wud explain the tightness.cheerstim Quote Link to comment Share on other sites More sharing options...
