Hey guys, I'm looking for some new spur gears and wondering if anyone knows where I can get some. Right now I'm running 109/29 gearing and my FDR is high so would like to get it down so I dont over rev my motor. Whats the biggest pinion you can go with a high count spur? All I find is 96+ spurs but not sure what pinion whould fit to get my FDR down. Thanks for any help..
