SRAM RED E1 AXS Power Meter Spider

SRAM RED E1 AXS Power Meter Spider

The SRAM RED E1 AXS Power Meter Spider uses Quarq’s premier DZero power measurement technology to provide accurate and consistent power readings. It is +/- 1.5% accurate and has active temperature compensation to make sure temperature changes don’t affect your power numbers. This power meter uses integrated chainrings to save weight and improve shifting performance. It also features dual ANT+ and Bluetooth SMART, left and right power balance and a full 2-year warranty.

Please note that SRAM offers their 52/39T, 54/41T, and 56/43T Red E1 Power Meter Spider in black only. They offer the 46/33T, 48/35T, 50/37T and in silver/black (pictured) only.

Advice From Our Staff:

This is SRAM’s premier 2x road power meter spider. The chainrings are fully integrated into the power meter which improves shifting while also making it lightweight and stiff. This power meter also measures power from both legs and provides left vs. right power balance. While the RED chainrings are made to last 50% longer than SRAM’s 11-speed chainrings, the chainrings cannot be replaced when worn since the rings and power meter are one piece. Most customers can get many years of life out of the power meter before it needs to be replaced and SRAM offers a 50% off replacement when needed.

Options For This Power Meter

Chainrings: The power meter is available in the following chainring sizes:

• 46/33T | 48/35T | 50/37T | 52/39T | 54/41T | 56/43T

RED 1x AXS Spider: We also sell the SRAM RED 1x AXS E1 Power Meter Spider which features a 1x aero chainring.
