First, the relevant information.
Rims: 615mm ERD. Sun Vista Cruiser
Front Hub: 100mm, 72mm across the flanges, so 14mm from axle face to flange face. 38mm spoke hole circle.
Rear Hub: 130mm, 57.3mm across the flanges. 50mm drive side, 30mm from the non drive side axle face. 49mm spoke hole circle.
Well, I know there's calculators out there, and I've used them. and well... here's the story.
I bought novatec hubs, and some Sun Vista Cruiser rims.
when I first measured the vista cruier rims I got a ERD of 603mm. .... and I got that answer a couple of times. I ordered spokes based on this. Which means I ordered 3/4 of my spokes 278mm, and 1/4 of them 280mm.
None of those spokes even vaguely come close to working on this combination of parts.
So, I put in my new ERD measurement, and got new spoke length measurements. 285mm for the front wheel, and 284/286mm for the rear wheel. I feer another 14mm of spoke length might not be enough.
Could someone check my work? :-) Please?
