Does anyone have any guidelines on building a budget 20" alloy wheels? In particular, I'm wondering about:
1. where to buy alloy rims (presumably 36 hole), what brand, at reasonable cost?
2. my old Royce Union folder has a 90mm fork dropout spacing and a narrow opening for a 9mm axle. I've figured out that a BMX wheel with a SLOTTED 3/8" axle will fit here while prying the forks open slightly. Anyone know where I can buy one of these?
3. is it possible to buy these narrow front hubs (91mm) anywhere? Old English 3-speeds had this spacing as well, I believe.
3. I'm thinking of an internal gear hub, so does anyone have spoke length data for particular hubs, e.g. Sturmey-Archer AWC or Shimano Inter-3? I'd probably go with 36 hole, cross 3 lacing. I've been told 7.25" works well but haven't actually tried it.
Thanks for any information you can provide.
