SRAM Red E1 2x Direct Mount Chainring Kit

The SRAM Red E1 2x Direct Mount Chainring Kit is a replacement chainring set for SRAM's flagship Red AXS crankset, sold in 46/33T, 48/35T, and 50/37T combinations so you can match gearing to your terrain. The kit uses SRAM's 8-bolt direct mount interface, compatible with Red E1, Red D1, and Force AXS cranksets built around the 8-bolt spider, and is designed for use with SRAM's Flattop chain on 12-speed Road AXS drivetrains.

Each pair of chainrings is machined as one piece rather than bolted together from separate rings, SRAM's approach to reducing flex and keeping shifts crisp under load on its current Red groupset. A 13-tooth delta between the big and small ring smooths out the cadence change during front shifts, part of what SRAM calls X-Range gearing, aimed at giving a 2x setup a wider usable range without the abrupt jolt of a tighter tooth gap. The aluminum rings come in a black/silver finish that matches the rest of the Red AXS groupset. For riders replacing worn chainrings or adjusting gearing on an existing Red E1 or Force AXS crankset, this kit swaps in cleanly without requiring a new crank arm.
