SRAM Rival AXS RD-RIV-E1

The SRAM Rival AXS RD-RIV-E1 is the gateway to high-performance wireless shifting, bringing the revolutionary 12-speed AXS technology to a broader range of cyclists than ever before. Engineered for both road and gravel, this derailleur delivers the same lightning-fast, precise shifting logic as the Force and RED tiers. Instead of the fluid Orbit damper found in higher models, the Rival AXS utilizes a dependable spring clutch system to maintain chain tension and ensure a quiet, secure ride over varied terrain. With a single cage length that supports up to a 36T cassette, it is the ultimate "do-it-all" component for riders who want the reliability of wireless electronic shifting without the premium price tag.
