Rear Wheel Mock-up Part III



The brake torque must be cut and shut to clear the 5” wide rim & 150 wide rear tyre.

I simply used an angle grinder to cut slots where I wanted the bend to occur. Once I am happy with the fit I will get it welded properly.

The upper photo shows the difference in the brake-torque-arms, the one on the left is the standard one.

Vintage Sumo with 5" wide rear wheel




I fully built the 5" wide rear wheel with the standard DR hub to satisfy myself (and others) that the hub and rim were compatible. That is all the angles of the spokes are right when laced together. The final build will probably use 5mm spokes rather than 4mm spokes.
I have been quoted $200 to supply the spokes in 5mm stainless steel, as the spokes that came with the wheel are not compatible. I have also been playing with the hub offset to ensure that tyre and chain clearances etc are OK.
Note also the rear tailight assembly with 'beehive' tailight. I am definitely going to swap the plastic indicators for chrome items with round lenses.
