Light, pretty easy to mount tires
- I've used it once or twice and have initial impressions

These wheels are very light, they almost feel fragile being this light. I needed to wet the tire bead with a little soapy water to help slide it over the rim and I was able to get it mounted without much trouble. Note that there are two drain holes in the rim, you can't see them in the pics. Those holes were not finished smoothly as they had a some carbon splinters, both rims were like this. SRAM confirmed that two holes is normal. I was able to seat 42 mm tires just using a floor pump, on the first try. No compressor needed. These definitely roll a lot faster than the aluminum WTB ST wheels that came with my bike. And the freehub is not very noisy either. I only have a couple rides so I can't speak to durability but so far I like the ride.

Bought a set of the new 303 Firecrest to use as road wheels on my gravel bike. I've put several hundred miles on them now and really, really like them. As they are hookless, getting my tires to pop onto the rims took a little more effort than I was accustomed to. But once I got the tires to set on the rims, they've been solid so far.

Are the 303 firecrest wheels made in the USA or overseas?

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?
