PLEASE SEE BELOW FOR CHAINRINGS!
SRM has taken power measurement to the next level with its SRM PM9 Origin Road Carbon Power Meter. Like all SRM power meters, the Origin features SRM’s 144 point calibration protocol, resulting in unmatched accuracy and consistency. The PM9 version also features Left/Right Power Balance, Magnet-less cadence, Automatic temperature compensation, and Bluetooth SMART, among other new features. The Origin also offers near limitless compatibility with exchangeable spindle sizes, crank arms, and chainrings – to fit any bike or ride preference.
This power meter is compatible with 110 BCD 4-bolt chainrings. It fits 24 MM, 30 MM or 29 MM DUB bottom brackets, depending on the version ordered. See Compatibility tab for more information.
This SRM power meter measures power at the spider and is therefore able to measure power from both legs.
Dual-leg power measurement, carbon crank arms, accurate to within +/- 1.0%, lightweight, rechargeable battery, 100 hours of battery life, left/right power balance, automatic temperature compensation, ANT+ and Bluetooth compatible, 2-year warranty. See Specs tab for more information.
It’s not cheap, but this is one of our nicest power meters. It is highly accurate, stiff, lightweight, looks amazing and comes with a solid 2-year warranty. You can mount a wide range of both 2x and 1x chainrings to it, from Shimano to Carbon-Ti to ROTOR and more. In addition, with an option to order it with a 24 mm, 30 mm or DUB spindle, you can put it on almost any bike.
While not listed in the dropdown menus above, you can bundle the SRM PM9 Origin Power Meter with a SRM PC8 Bike Computer. When you do, you get $249 off the standard price of the PC8. Please contact us if you would like this option.
Here are the most commonly ordered chainrings with this power meter. You can simply add them to your cart along with your power meter and we will install them for you.
Chainrings: The SRM PM9 Origin is compatible with any 110 BCD 4-bolt asymmetric chainrings (Shimano, SRM Aluminum, Carbon-Ti, ROTOR, etc.).
Bottom Bracket: This power meter fits 24 MM, 30 MM or 29 MM DUB bottom brackets, depending on the version ordered. If you are ordering the same size as you currently have on your bike, you should be able to re-use your existing bottom bracket.
