We wanted lightness, stiffness, and durability, and we achieved all three. Our one-piece construction ensures none of your effort goes to waste. A 13-tooth delta on all chainring pairs ensures precise shifting for any setup, as well as less dramatic cadence changes during front shifts. And the technology we've incorporated makes this our most durable chainring set ever.

• Crisp and precise front shifting
• One-piece construction for faster, smoother and safer shifting
• X-Range shifting technology gives you greater range and smoother progression, so you'll always be in the right gear
