SRM PM9 Origin Road CYBREI Power Meter

The SRM PM9 Origin Road CYBREI Power Meter is truly one of our nicest builds. Starting out with the power meter, the SRM PM9 uses a 144 point calibration protocol resulting in unmatched accuracy and consistency. It also features Left/Right Power Balance, Automatic temperature compensation and Bluetooth SMART, among other new features.

In addition, the CYBREI Crankset is one of the lightest, strongest carbon fiber cranksets ever made at only 331 grams (crankset and DUB spindle). While it features a DUB spindle, you can use it with 30 mm bottom brackets as well, when used with the 30 mm adapter (included).

Advice From Our Staff:

When you pair the new PM9 with the CYBREI crank arms, you get a highly accurate, very lightweight, beautifully looking power meter crankset – truly a dream build. In addition, you can mount a wide range of both 2x and 1x chainrings to it and can use it with either DUB or 30 mm bottom brackets, so there is maximum compatibility here. The drawback is the price. It’s a It’s an expensive power meter crankset so it’s not for everyone.
