Same gear ratio with a smaller ring?

Hi Lee,
I just got a Black Market MOB and want to run a gear ratio (single speed) as close to 36-17 as I can, but with a smaller front and rear sprocket. Can you tell me how to compute this or just tell me what the closest is?

Hey Justin,

Chainring / cog = ratio

36 / 17 = 2.12

Chainring / ratio = cog

Say you want to run a 32 up front.

32 / 2.12 = 15.1

You can rock a 32 x 15.

Braaap!
