Cool..

I found the specs for the bike.. so should be 67t/30t .. plugging numbers into Sheldon's calculator gives around 45 to 82g/i .. I can see that being a little aggressive for that style of bike.. first thing would be to get a 60t .. that would bring it to 40 to 74 g/i.. and I think I have a 32t that would fit the Nexus, in fact, I may even have the 60t .. that would get you your 20% reduction at 37 to 69 .. that would make for a much more usable bike.. to find a belt, measure your center to center and input figures into an online belt calculator .. then see if an 8mm HTD belt is in the catalog close to what you need ..
