Ball Shifter is 3 cim Ball Shifter using 2 Cims with a 2.65 spread. The pinion gear attached is 12 tooth and the wheels have a 30 tooth gear on them.

The Single Speed is a WCP with 2 motors with a 44:30 ratio attached to the same gears on the wheels.

Wheels are 12 inch pneumatic taped to reduce friction.

Let me know what else you need.

Thx,
Daniel

Does the clicking noise happen all the time? We got the same noise in our ball shifters in the offseason, but only when we tried shifting *with low air*. What pressure are you using to shift?
