hmmm mine has a 15/16" axle nut and 5/16" adjustment bolts

I use a chain adj. bracket that attatches to sprocket to align chain up (I used to eyeball/count notches and or threads, but wasted a sprocket that way)

I also got around 32mpg to 36mpg with 16 tooth and I get around 34mpg to 38mpg with the 19 I have now.


course it might have more to do with riding style
