Hi, I'm fairly new to riding fixed so would appreciate some guidance...
I'm currently riding with a 45 tooth crank and 17 tooth cog - a ratio which is really good for me.
I've just acquired a 51 tooth crank and was wondering roughly what sized cog to use which will be similar to the ratio i;ve got at the moment.
Any advice would be appreciated.
^Go there and start plugging stuff in. I don't know your crank arm lengths or tire/wheel size, but once you plug everything in it'll give you a list of equivalent gears.
Oh, you know...
Middle school math.
45/17 = 51/x
(45/17)/51 = 1/x
51/(45/17) = x
x = 19.26666
19 is a bit taller, 20 a bit more lower.
Maths be gone!
