While I didn't use the wheels from Jenson, I did buy the Alex 404 rims from Nashbar and laced them to an extra pair of Schwinn hubs for my '72 Continental. $14.99 each for the rims. I only have a few miles on them because I also switched out the crank and I'm hunting for a front derailleur, but they seem to be a solid and true pair of wheels.
