Re: Rear Hub too large for Sproket adapter..PLEASE HELP!
I would avoid all the hassle of rebuilding an old wheel.
Is your wheel perfectly true, and in "round"?
Is the coaster brake hub on it serviceable, and parts available?
You already know the spokes are gone.
I would just head to a local bike shop and order a new wheel.
The vendors who advertise here have good quality wheels too.
Get a good wheel. If you can get one with 11g spokes and drum brake!
