I love these wheels. Felt improved performance from the first pedal stroke. I bought a larger tire because I thought the 25 would not give the comfort. I was wrong. The pairing of the tubeless rim and 25 mm tire is perfect. Best upgrade I have made in a long time! I highly recommend this set up.
As Adaptors go, I find this brand to be a good one. It matches my DT Swiss hubs exactly, with none of the mixed off-brand mish mash that I find so dreadful to have to tolerate looking at. This esthetic gives me ultimate confidence that when I grab a handful of brake, my bike's forward momentum will be reduced in a most pleasing, eye-appealing way. Safety too, is enhanced using products designed to be an integral, cohesive unit.
Not the lightest wheels you can get at this price. Not the cheapest you can get a wheelset of this weight. However, the Zipp 30 Course is arguably one of the highest quality and best values. The wheels rim width offers versatility for a wide range of tires for road, cross, and gravel. The 30mm rim depth offers some aero benefit while limiting the effect of cross winds. They're well designed, built, and strong (compare the max PSI and rider weight limit) and per the specs are even a bit lighter than the Zipp 302 Carbon wheels.
I recently purchased these and even though they came with 40mm Yksion Allroad tires installed I wanted to test out Mavic's UST tubeless. I removed one tire completely and reinstalled it. Seated within seconds using a simple floor pump. As soon as pressure got near 20 psi the tire popped into the beads. Easy as that. I deflated, added sealant, reinflated and it held air perfectly. Hubs are smooth, build quality seems strong, and although not the lightest wheels out there I dropped a full pound and a half off my gravel bike by replacing wheels, cassette and rotors.
