The only constant is change. Today's XC race machines are marvels of modern engineering, evolved to decrease weight while improving ride quality and durability, with the idea to carry the world’s best athletes to the top step of the podium.The Reserve 28|XC is the race-ready culmination of everything we’ve learned from years at the highest levels of competition, and it delivers on a heap of promises. At a genre blurring 1300g for a complete wheelset (with no rider weight limit and our market-defining lifetime warranty), the 28|XC features a new wider and lower rim profile to increase strength and lateral rigidity, while adding vertical compliance for enhanced traction. The new rim shape also eases tubeless tire installation and improves tire bead retention at lower pressure. The Reserve 28|XC is really the go-to wheelset for the modern XC bike: Sturdy and strong enough for a rowdy XC ride, but light and fast enough for a jaunt on the World Cup XC circuit.
