Belt drive fixed

just had a look at the rear stays/crank/cog. if it's centered over 10mm, it will fit.
even then, i have a 45t x 17t you could go smaller on both and have more room.
how wide are the belts?

There's no 17t sprocket as the carbon fibres in the belt dont like to bend that sharply. So you're looking at a 20 : 55 ratio for road use.

The belts are something like 15mm wide. I can measure it tonight.
