What replacement wheels/rims that can be fitted into
Raleigh Twenty bike are available these days?
Below I focus my requirements on the rims as they are probably easier to come by than complete wheels but if there are new wheels available then I'd love to know the vendor/manufacturer.
Ideally I would like not to modify anything and stick with
20" × 1-3/8" size with
28 spokes taking
ISO 35-451 tyres if such option exists at all.
The next acceptable option would be same size with
36 spokes which would require replacing the hubs (which I hope can be obtained more easily).
Yet another possibility is any other wheel size that would fit the bike without modifications (with the exception of the hubs).
The least acceptable option would be a solution requiring mudguards removal, front fork replacement, brakes change etc. However, out of curiosity I would be happy to see what more drastic routes can be followed.
