SRM PM9 Origin SRAM RED E1 Power Meter Crankset

SRM PM9 Origin SRAM RED E1 Power Meter Crankset

The SRM PM9 Origin SRAM RED E1 Power Meter Crankset combines the SRM PM9 Origin 8-Bolt spider with SRAM RED E1 carbon crank arms. This dual sided SRM power meter measures power from both legs with accuracy rated at +/- 1.0 percent and weighs just 122 grams. It also features a rechargeable battery with up to 100 hours of ride time, active temperature compensation and left and right power balance data. To ensure exceptional consistency, SRM applies a detailed 144 point calibration process across all riding conditions.

This crankset uses SRAM RED E1 carbon crank arms, which are the lightest and stiffest road crank arms SRAM has produced to date. SRAM reduced weight by 29 grams compared to the previous generation while retaining the proven DUB spindle for broad compatibility. Riders can choose between a standard road spindle or a gravel focused XPLR spindle. The XPLR version increases Q-factor for improved tire clearance and better support for modern 1x gravel drivetrains. With crank lengths ranging from 150 mm to 175 mm, riders can dial in fit for nearly any setup using the SRM PM9 Origin SRAM RED E1 Power Meter Crankset.
