Can anyone tell me how you work gear ratios into inches?
For instance i ride a singlespeed road bike with a 42 tooth chainring and a 16 tooth cog.
What's that in inches?

If this is in relation to underage gearing, its usually the distance the wheel travel for one crank revolution.0

That was the method that used to be used for junior racing but generally the gears are refered to as inches but it does not mean how far the bike will travel for one rev.Calculation is number of front teeth divided by back teeth x 27.Vino2007 wrote:If this is in relation to underage gearing, its usually the distance the wheel travel for one crank revolution.
ex 52 x 13 = 108" 42 x 21 = 54".
That used to be the standard top and bottom gears on the old racing bikes years ago
