Hello..
I have a 20" lightweight rolf wheel (kinetix pro for dahon), it has an american classic free hub, which is strangely noisy when clicking free. Anyway, shimano capreo hubs have a cassette with 9 and 10 tooth sprockets for higher gearing. I've built a racer but the highest gear is not nearly high enough at 11t on a 20"wheel. I might pick up a 60t chain ring. Anyway my question is, ..
The American classic hub is 75mm in diameter but the shimano is 55.there are 8 spokes hooked to each side of the hub. The shimano hub is 32h so 16 holes on each side This means I could use half the holes for the paired spoke of the rolf wheel. This means that the spokes would be around 6mm further apart than when on the original hub, and it also means they'll be about 10mm closer to the axle.
This means the spokes will be basically the same length, but rotated towards the centre of the wheel slightly. (less than 1degree i think)
I would love to hear from any engineering minded wheel person whether this will work or be unstable somehow. I've added a photo of the current wheel and a hub with the new formation of holes that I would use half of to spoke in the same way as the original. Any advice most welcome! Would be a shame to be whizzing along and for the wheel to disintegrate.. Thanks
