The lowish speed is 11t to 65t, using the VEX pinion. The faster speed is 17t to 60t. I designed it to use a 3.6" custom wheel. This means that the 65t gear is dangerously close to the carpet. that's why its made from steel as apposed to Al. lol

Keep in mind that tread wears. Unless the wheel is going to have a tread on top of the 3.6" diameter, in which case it will be fine.
