It's been over a year since we first placed our order, but we finally
have received Shimano Nexus 8-speed hubs.

I bought one myself, I'll be doing it up with 650B rims...

Okay, I've read the Rivendell ode to this rim size, but aside from
acting as some sort of revivalist preservation of the rim and tire
standards so future generations can roll along on mid-century French
bicycles, the attraction is purely aesthetic, right?

Or is there some advantage to spanning the 559-622 mm interval I haven't
perceived? Maybe a compromise for 29er-like off road virtues but with
stronger wheels?
