SRAM RED AXS E1 Power Meter Chainring 12 Speed Size:50/37t 75 oz (Medium)The SRAM RED AXS E1 Power Meter Chainring adds Quarq technology to a one piece chainring design for the lightest, stiffest and most accurate power package available. A consistent 13 tooth delta across all chainring pairs ensures precise shifting for any setup, plus a less dramatic cadence change during front shifts. Combined with SRAM's most durable chainrings ever, it's an unbeatable combination for serious training and racing. Features X Range
