I've had a hard time finding a good selection of tires that's around 28-28.5 inches in diameter. I find A LOT more in ~27 inch area which is stock diameter.
Huh?
Most stuff that's desirable and available in the 27" area is 255mm or less. That sucks.
W/a 28.5" tire and 4.10 gears I'm at 2500rpm doing 75mph down the road. 3.90 final ratio.
