ScotchDave Posted January 13, 2006 Report Share Posted January 13, 2006 18:16 is the usual.18:16=1.12518:14=1.28622:18=1.222Based on this you have to decide, if you want to calculate any more rations the way to do it is divide the chainring by the cog.

nafan Posted January 13, 2006 Report Share Posted January 13, 2006 Used to run 18-18 on my pitbull, but now I use 18-16 and it's much better...Only use 18-14 if you want a gear 6/7 ratio Best off with 18-16 mate Nathan Quote Link to comment Share on other sites More sharing options...
