SRM PM7 Origin Road Carbon Power Meter

SRM has taken power measurement to the next level with its SRM PM7 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 close to just 600 grams when ordered with the LOOK Carbon crank arms!

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.

Options

    Really easy company to work. The process to buy a power meter and the post buying it’s been 10 of 10. All info you need you gonna get it. Also really quick shipment process for get your power meter in Europe. If I have to buy another powermeter I will use again this site with no doubt.

      Thank you so much, David. It was a pleasure doing business with you! If there is anything else we can do, please let us know! Ride safe!

    The origin is a wonderful power meter. It almost looks like a work of art. Works great with my Dura Ace chain rings. It’s probably psychological but I feel like I’m generating more power with the stiffness of the carbon crank arms. Wattage is nice and accurate, no need for all the fancy data, just pure accurate power.
    Easy to install and paired right up with my wahoo bolt. Cadence sensor was easy to install on the bottom of the bike with the included 3M tape.
    Power meter city provided me with a wonderful experience. Josh was a delight to work with and the service and communication was flawless. I will definitely come back again for any power meter or other accessory need. Great job guys. Thanks.

    The Origin is the best and amazing. It . It’s obviously beautiful, everyday went riding it become like to have more km to roll and roll performance seems to be out of this world good. Readings are instantaneous, consistent, and oddity/fluke free. The carbon crankarms feel wonderfully stiff just a really solid set to push THAT IS NO ERROR At all the best ever power meter

    Best Power meter Hands Down !! I have had Pioneer, Garmin Pedals, Quarq power meters and by far I have never have a drop inn power or issue with accuracy using SRM they just work. Now SRM is ant+ only and will not give you all these crazy metrics but all i want to look at is power and only use while riding outside never on a trainer. With Garmin I had endless drop out issues and right pedal missing 10 times while riding then 5 min waiting period for calibration. Pioneer has been better I use on my other bike and don’t have issues but sometimes It takes 2 or 3 times to calibrate. The SRM is so simple !! My previous SRM lasted 7 years before I had to have battery replaced. Hopefully I will get similar results from the SRM origin.

    The Origin is simply amazing. It’s been set and forget and flat-out perfect performance from day 1. I’ve got 980 miles on it thus far and simply can’t rave about it enough. It’s obviously beautiful, but the performance seems to be out of this world good. Readings are instantaneous, consistent, and oddity/fluke free. The carbon crankarms feel wonderfully stiff…. like when I switched from Giro to Bont shoes…. just a really solid set to push against (of course this might be psychological, but… it’s still awesome). I’m going to be testing out moving from 172.5mm down to 170mm crank length in a week or so, which is just another fantastic option that you get with the Origin.

    • Power Meter City

      Hi K. Hassell. We are absolutely thrilled to hear the SRM Origin is everything you wanted it to be. We know you waited a while for it and it sounds like it was worth the wait – awesome stuff! Happy training good luck with the 170 mm setting!
