Gearing range problem
The track I run on likes about 95mm of rollout for 17.5 blinky. I'm just building my X12, and I'm having trouble getting a large enough pinion to fit. I have a 76 tooth spur (it seems hard to find smaller ones) and the largest pinion that will fit is a 52 tooth, which gives around 90mm with 41-42mm rear tires.
Should I just run larger tires, or try to find a 74 tooth spur? Any solutions?
