mcman56 Posted December 21, 2008 Report Share Posted December 21, 2008 Does anyone have a sprocket recommendation on a C15 for Trials? I would prefer to stay away from a huge back sprocket and am really only concerned about getting first low enough. This bike has the 33/17 first gear....listed as wide ratio in the RR book. (Oddly the other gears match the close ratio numbers in the book.) From what I can tell, the smallest transmission sprocket is 13 tooth and the smallest motor sprocket is 18. With the existing 56 rear sprocket, I calculate an overall 1st gear about 24:1. The same calculation for my Reflex with 9/44 final drive gives me 45:1. Am I missing something?
