Sram:

Stiff, strong chainrings form the backbone of our best front shifting ever. Rival 2x chainrings are a light, elegant one-piece construction so none of your effort goes to waste. A 13-tooth delta on all chainring pairs ensures precise shifting for any setup, as well as a less dramatic change in cadence during front shifts.

Features

• Crisp and accurate front shifts
• One-piece construction for faster, smoother, more secure shifting
• X-Range gearing technology gives you more range and a smoother gear progression, so youre always in the right gear
