Well that was entertaining!
Tried three different online spoke calculators to try to nail down correct spoke sizes for a wheel build for this puppy and got three different results back using the same info!
Don't have the patience for this. Measured everything in the shop and did a trial build using DT Swiss Champion spokes, which worked out just fine - and gave a different spoke length again. A simple cross three shouldn't be all THAT complicated to standardize.
But there'll be a couple more wheel sets to build - at least now when I order those Alpine III's I won't be wasting my time.
On the other hand, my 'dumb' axle modification made for a clean installation at the front end.
And the Schwalbe 700 x 50c tire has lots of clearance at the front end - cheapest front end suspension system on the market.
And the Token chain-ring bolts were a pretty good match for the crank
