I have not recieved the 12T yet. I am not running a chain guard and maybe would like to try the CA160 rear sprocket. I counted the teath on my front sprocket and I am currently running 36/14 = 2.57. I found one on ebay and I think I am counting 37 teeth, does that sound right which would equal 37/14= 2.64 or a 2.87% improvement, not much, but maybe it is enough to get me up to 50 mph consistently. what do you guys think?
