I'm looking at getting some new commuter wheels and I'm on a budget. Nashbar has a set of Ultegra hubs (28F/32R) laced to Mavic CXP33 rims for $199. I can't think of anywhere that I can buy the rims/hubs/spokes for even close to that price. Does anybody have experience with Nashbar builds? I'm assuming their wheels are machine built. I know that the wheel build is a big part of the wheels strength and longevity, so even though it seems like a good deal - is it worth it? Would I be better off buying them and then backing everything off and re-truing/tensioning them?
