SRAM RED E1 AXS Power Meter Crankset

SRAM RED E1 AXS Power Meter Crankset

The SRAM RED E1 AXS Power Meter Crankset is Quarq’s flagship road power meter crankset. Using DZero power measurement technology, this SRAM power meter provides accurate and consistent power readings. In addition, with active temperature compensation, changes in temperature won’t affect your power numbers. It also uses integrated chainrings to save weight and improve shifting performance. The power meter features dual ANT+ and Bluetooth SMART, left and right power balance and comes with a full 2-year warranty.

The RED E1 AXS power meter crankset features SRAM’s latest carbon crank arms. Thanks to a new and optimized carbon layup, these are SRAM’s lightest road cranks ever. The continued use of a DUB spindle means they are compatible with a wide range of frames and bottom brackets. Additionally, SRAM has added new crank lengths, including as short as 160 mm.

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 crankset. It is 29 grams lighter than the previous generation and is available in more crank lengths. We also like that the power meter 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, please note that 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.

Other Versions to Consider

SRAM RED E1 Power Meter Spider: If you already have SRAM RED AXS crank arms and are looking for only the power meter spider and chainrings, we offer the SRAM RED E1 AXS Power Meter Spider.

SRAM RED E1 1x Power Meter Crankset: We also sell the SRAM RED E1 1x AXS Aero Power Meter Crankset. This power meter crankset features the same carbon crank arms, but uses a 1x aero chainring.

Force Power Meter Crankset: This power meter also comes in a Force version. The SRAM Force AXS Power Meter Crankset is not quite as light and stiff as the RED version, however it is more affordable.
