So, i just saw that Rolf Wheels came out with a new version of their carbon rims. These are 60mm deep and another $100 over the current version. The dilemma for us now is, do we get a pair. We have almost 2700 miles on our new custom Calfee Dragonfly with the current Rolf carbon wheels on it. When we spec'd the bike, Rolf was the only maker we could find that would warranty the tandem wheels for use actually on a tandem. I am aware of other wheel builders and such that would put a wheel together for us, but that didn't work out. We love the Rolf carbon wheels so an upgrade would be just for kicks. We are a light team - about 265, plus 27 pound bike. any thoughts?
