SRM PM9 Origin Track Carbon Power Meter

The SRM PM9 Origin Track Carbon Power Meter is the latest offering in SRM’s new Origin power meter line. With the Origin, you not only get SRM’s +/- 1.0% accuracy levels and unmatched consistency and durability, but also LOOK carbon crank arms. Weighing a mere 120 grams and featuring ultra-stiff carbon fiber, the LOOK carbon crank arms give the Origin a superior stiffness to weight ratio. In fact, the entire power meter weighs just 599 grams.

In addition, the LOOK crank arms feature Trilobe Technology, which allows the crank arm to function in three lengths, 170 mm, 172.5 mm and 175 mm, simply by rotating the Trilobe pedal inserts. The Origin also offers near limitless compatibility with exchangeable 24 and 30 mm spindles, which means it can be used with virtually any frame on the market.

Crank Arm: LOOK-SRM Carbon | SRM Carbon Composite

  • LOOK-SRM Carbon (170/172.5/175) – These are the lightest crank arms offered (260 grams). The crank arm functions in three lengths, 170 mm, 172.5 mm and 175 mm, simply by rotating the Trilobe pedal inserts.
  • SRM Carbon Composite – These carbon arms are still very light and stiff, but they weigh a bit more than the LOOK-SRM Carbon at 344 grams per set. However, they are also more affordable.
