The new SRM Origin PM9 brings useful new features and compatibility to their benchmark spider-based power meter for road, gravel, and mountain bikes.

Using a new design that still works with their modular system, you can mix and match spindles, crank arms, and chainrings to fit whatever bike you’ve got, and now it’s much easier to charge and use…

The biggest upgrades for the new PM9 are:

  • Magnetless cadence measurement
  • Oval chainring compatibility
  • Left/Right balance
  • Pedal Smoothness
  • Temperature Compensation

Now, there’s no need to stick a magnet on your frame for it to detect cadence. As much as we enjoy seeing some of the clever mounting solutions, this is a big user-friendliness upgrade.

A built-in temperature sensor lets it automatically correct itself in real time, and improved angle and torque measurements allow it to maintain accurate readings even with oval and other non-round chainrings.

The 9th generation PM9 uses a magnetic charging port and is available as a Mountain Bike version, too, just without the same graphics and “9” mark. They have ANT+ and Bluetooth LE transmitters to work with most any modern cycling computer, and it’s own app can show more advanced pedaling dynamics data. And yes, it’s Zwift compatible.

They offer a variety of spindles to fit different bottom bracket standards, and their crank arms come in alloy, carbon, and top-level Look carbon fiber versions to fit different budgets.

All use the same PM9 spider, which allows you to fit the product to almost any bike and rider. Not shown, there are also SRAM, Shimano, Praxis, and Campagnolo crankarm/chainring versions sold as complete kits with the new PM9 spider.

SRM X-power mountain bike power meter pedals

The X-Power power meter mountain bike pedals are now being assembled in their Colorado-based US headquarters, too, which should improve availability and shipping times for North American customers.

They use a magnetic charger, too, with only a single contact port for one lead…the spindle is the other contact. Available in Orange, Gold, Blue, Black, and Red. MSRP is $1,199 for a dual leg pair, and $899 for a single leg setup with a “dummy” pedal on the left side.
