Cold Fusions aren't even rebadged Fusions. They are Fusions. I bought a pair from IRO and they arrived in original Velocity packaging. The only thing that said "IRO" was the shipping invoice.

You are only "supposed" to run up to 28-32c tires on 19mm rims (like the Fusion, CXP22, Open Pro, etc), but I've run up to around 45-50mm tires on road rims and been just fine. The profile of the tire will be rounder/narrower than if you used a wider rim, but they'll work just fine. All kinds of people regularly race 'cross on 32-35c tires on narrow road rims.
