NotSoBigBen Posted August 25, 2008 Share Thanks Jabba, that makes more sense. So according to that 4th in granny is pretty equivalent to 1st in middle. Cool! Link to comment Share on other sites More sharing options...
GoLefty!! Posted August 25, 2008 Share 32-28-24-21-18-15-13-12-11, 22/21= 1&1/21 or 1.048 32/1.048 = 30.54 or as near as dammit to 31 so the closest gear is 32/32 or 29/28 Link to comment Share on other sites More sharing options...
