I have been riding these wheels for about two months now and I feel that I can provide some insight into how they perform. Installation: After receiving the wheels I installed a pair of 28 mm SCHWALBE Pro One Evolution tires. The tires mounted without the need for an air compressor and inflated with a floor pump. Both wheels showed some leakage around the valve stems initially but this quickly sealed when the Stan’s sealant was injected and there were no issues with their holding air subsequently. This is the 5th tubeless installation that I have performed and it was by far the easiest. Performance: I was initially skeptical regarding the tire pressures recommended by Zipp for these wheels. For a rider of my weight, around 200 pounds, pressure of 65 psi in the rear and 60 psi in the front are recommended. As it turns out these pressures work very well. The 28 mm tires have taken on a very low and wide profile and dampen vibration and grip well with no squirming suggestive of inadequate inflation. After about 800 miles of riding I have had zero punctures. The freewheel is loud and I like the sound. There have been no issues with the hubs so far. Initially the bearings seemed sluggish, but after a few hundred miles they spin well. The wheels have remained true despite some punishment and appear to have been built well. I am unable to comment on the claims regarding power savings due to the improved compliance but I will say that the wheels feel fast. This is especially noticeable on chipseal roads and broken road surfaces, where there is a sensation of giving up less energy to the road than with other wheels that I have used. The wheels perform well in crosswinds despite their medium depth. Overall impressions: I think that this is an excellent wheelset and a great choice for the type of long distance riding that I do, where the compliance is very much appreciated. They look great. They are not inexpensive but I think that they are a good value given the quality and should last for many years.

Was curious... is the minimum tire width 28mm? Can I use 25mm with these wheels? thanks.

How do we order these with QR release skewers? How do we order these with the disc rotors attached?
