Single speed setup on a road bike with vertical drops.
Chain is just a tad too tight.
Current chain ring upfront is a 48.
I have noooo idea how much difference taking away just one tooth will make if I change it out.
Should I try a 47 or 46 or 45 or.... ?
I know you can't tell for sure without seeing it but maybe you can give me some kind of idea?
And which would make a bigger difference? One tooth less on the front chain ring or one tooth less on the rear sprocket? Current rear sprocket size is 20t.
The rear is an i-motion 9 speed internal geared hub so I can play around with sizing more than a standard single speed.
