SRAM Rival 107BCD Chainrings

A tight and consistent 13-tooth gap between chainrings delivers accurate and dependable shifting and is the core of our X-Range gearing. Our smaller chainrings paired with wide-range, 10t-start cassettes provide more efficiency and more time in the big ring. It’s modern gearing for today’s riders.

• Crisp and accurate front shifts
• Durable finish
• X-Range gearing technology gives you more range and a smoother gear progression, so you're always in the right gear

X-Range
Road bikes are faster and more capable than ever before, and riders are expanding what’s possible with drop bar bikes. X-Range is geared for today’s road riding. We completely reimagined road gearing for a wider range, more useful and smoother gear progression, as well as smarter shift settings—enabled by AXS. With X-Range, you’re always in the right gear.
