nafan Posted January 2, 2006 Report Share Posted January 2, 2006 You'll have to use something 125mm+ I would say, I have an 18 tooth echo cog on my 05 and it rubbed slightly on the stay with a 110mm xt bbGo safe and run a 127.5, I use a neco from selectbikes, cheap too Nathan Quote Link to comment Share on other sites More sharing options...
Tom Booth Posted January 2, 2006 Report Share Posted January 2, 2006 Its probably the same tom...The BB is just to make the right spacing for chain alignment The wide bb is to clear the chainring of the yoke..I bet you could get away with a 124..122??Tom Quote Link to comment Share on other sites More sharing options...

nafan Posted January 3, 2006 Report Share Posted January 3, 2006 You probably could get away with 122 indeed, however I'd play same and get a 125+ No point in ending up with large chunks taken out of your frame like I did Quote Link to comment Share on other sites More sharing options...
