SRAM RED Quarq E1 AXS Power Meter Kit Ratio:50/37T thanks to the towbar coupling'sThe RED AXS power meter kit adds Quarq technology to SRAM's one piece chainrings for the lightest, stiffest, and most accurate power package available. 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. Combined with SRAM's most durable chainrings ever, its an unbeatable combination. Power Meter including Chainrings, FD setup tool
