I got good news and bad news, good news is my sheave fits right on a 700c Measurements in mm indicated by rim 700c 622 x 20mm By tire 700c x 38 tire size Bottom line is where I'm getting at my sheave hits a tiny bit can I put spacers between the axle bolts? Or should I get axle nut screws to get clearance ratio and a slightly longer chain to compensate dimensions? Sorry no pics yet had to jump in quickly to get to work. I think it will take 2-4 axle nuts. 1 for both sides or two per side I'm so ready I can do a Wilson baseball slide "go hawks." Also decided on painting as well.. Blue and black... Preferred flat for easy touch ups.
