As road bike designs continue to evolve to be faster than ever before, we need new components that are durable and trustworthy at high speeds. The Rival 12-Speed Chainring is one of the most dependable modern gearing options, providing you with fast and efficient shifting. SRAM uses a 13-tooth gap between chainrings and X-Range gearing technology to create a smooth gear progression and ensures you are always in the correct gear. When installed and paired up with a wide-range cassette, more time is spent in the big ring, allowing for a more efficient ride.
