SRM PM9 Origin Road Carbon Power Meter

SRM has taken power measurement to the next level with its SRM 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. However, for the first time, the SRM Origin power meter uses a LOOK carbon crank arm which offers superior stiffness to weight ratio. In fact, the SRM Origin weighs a mere 599 grams!

In addition, the LOOK crank arm features 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 30 and 24 mm spindles, which means it can be used on virtually any frame on the market.

 

SRM Origin Power Meter Highlights

Precision Accuracy

SRM uses a 144 point calibration protocol against a known mass measured to the exact gram. With precise calibration and its Auto-Offset feature, the Origin is accurate to +/- 1.5%.

Super Light and Stiff

Featuring LOOK carbon crank arms which weigh only 99 grams each, the SRM Origin offers superior stiffness to weight ratio. The entire power meter weighs in at only 599 grams!

Compatibility and Convenience

By simply rotating the Trilobe pedal inserts, the Origin offers three crank arm lengths: 170, 172.5 and 175 mm. In addition, with an exchangeable spindle design, it can be used on a wide variety of frames.

Battery Options

You can purchase the Origin with either SRM’s proprietary battery – which features 1,900 hours of battery life – or upgrade to a rechargeable battery for maximum convenience.

Options

Crank Arm:

  • Carbon Trilobe – These are the lightest crank arms offered (260 grams). The crank arms function in three lengths, 170 mm, 172.5 mm and 175 mm, simply by rotating the Trilobe pedal inserts.
  • Carbon Composite – These carbon arms are still very light and stiff, but they weigh a bit more at 344 grams per set. However, they are also more affordable to purchase. They are available in 170 and 172.5 sizes only.

Note – we also have SRM Origin Aluminum Campagnolo Chainrings available.

Compatibility

Chainrings: The SRM PM9 Origin is compatible with any 110 BCD 4-bolt asymmetric chainrings (Shimano, SRM Aluminum, Carbon Ti, ROTOR, etc.). We offer this power meter with SRM Aluminum or Carbon Ti rings, however you may also use your own as well.

Please note, this power meter is compatible with the new Shimano Ultegra 8100 and DURA-ACE 9200 chainrings.

Bottom Bracket: This power meter fits 24 MM or 30 MM 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. However, if you are chaining spindle sizes, you will need to replace your bottom bracket. Please contact us with questions, we are happy to help.
