SRAM RED AXS Powermeter 2x Chainring Kit | Direct Mount | E1 - black / silver

Effortless performance. Effortless perfection.

It’s the ultimate in integrated power measurement. The RED AXS power meter kit adds Quarq technology to SRAMs one-piece chainrings for the lightest, stiffest, and most accurate power package available. A 13-tooth gap on all chainring pairs ensures precise shifting for any setup, as well as a less dramatic change in cadence during front shifts. Combined with SRAMs most durable chainrings ever, it’s an unbeatable combination. The power meter is accurate to +/-1.5% and isn’t affected by temperature changes.

Features:

• Crisp and accurate front shifts 
• One-piece construction for faster, smoother, more secure shifting 
• Power meter is fully integrated into the chainring
• Power balance measures separate values for the left and right leg
• X-Range gearing technology
• Available in different chainring combos

X-Range™

Road bikes are faster and more powerful than ever before, and riders continue to show what bikes with road handlebars are capable of. X-Range™ is the gear ratio for the modern way to ride a road bike. SRAM has completely redesigned the road bike transmission, for more gear range, a more pleasant and more usable gear gradation and thanks to AXS™ also smarter shift settings. With X-Range™ you are always in the right gear.

AXS™

AXS™ is SRAM's integrated wireless platform for connecting electronic bike components with software. The SRAM AXS™ app allows riders not only to check battery levels, influence shifting behavior and configure controls according to personal preferences, but also to create maintenance schedules and update firmware.
