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.
 
The best would be a frame spreader, like small block chevy exhaust manifold spreader, put a tempeary axle in to hold the width and spread the front..............Curt

SBC ram's horn spreader?
How would you do that?


1. Measure how much clearance you'll need.
2. Remove the rear wheel and sheave..
3. Bolt a length of all thread where the axle would go.
4.Place a hydraulic jack or a scissors jack from a small vehicle
between the front seat stays, where the cantilever brakes are.
5.Keep spreading the frame until you
get the necessary clearance.
6. Do the same at the chain stays, if needed.

The extra washers or nuts you'll need when you place
the rear hub onto the frame will serve as spacers,
not frame spreaders.
The spacers will not be spreading the frame.
The spread was accomplished by the jack.
