At 26-36 I get gear inches of 19.5 if I did the calculation correctly. I get rollout of 61.26 inches at 26 versus 70.69 inches at 30.

Gear ratio is .72 at 26 versus .83 at 30. At a cadence of 80 I get a speed of 4.64mph at 26 versus 5.35mph at 30.

Somebody please check the calclations.

I don't know if that's significant or not. It's about a 13% reduction in gear ratio and gear inches.
