SRAM Red E1 Chainring Kit 12 Speed 50/37T

Our lightest, stiffest, and most durable chainring. Our one-piece construction ensures that 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. And the technology we’ve packed in makes this our longest-lasting chainring set ever.
