It will if you are running single speed 1/8" chain now .. check what it says on your existing cog... if 3/32", then a 1/8" cog won't work, unless you have a single speed chain like the SRAM PC-1 chain.. that's another reason to move to a different crank, then you can use 3/32 cogs which I think go down to 15t..
