A beautiful marriage

This version of the SRM Power Meter features a larger diameter than Shimano's 7900 version. This adequately accommodates the larger FC-9000 crankset. In addition to allowing the crankset to fit properly, the new platform also provides more accurate measurement of the offset forces and torque patterns for your left versus right leg, which means more accurate overall power measurements. The wider diameter holds two batteries, which equates to almost 3,000 hours of use before needing to be recharged. SRM uses its tried and true eight strain gauges for measuring data. The 9000 Power Meter features an accuracy of +/- 2.0% between 30 and 255 rpm, with a wattage range between 0 and 4096 watts, for that wild finishing sprint.

The FC-9000 crank is the same Dura-Ace crank being touted for its versatility. You’re able to run compact or standard rings on the same spider. Thanks in part to the four arm design, it is also lighter than, but just as stiff as, its predecessor. It uses Shimano’s Hollowtech II and Hollowglide technology to create a stiff yet lightweight design with an unrivaled weight-to-stiffness ratio.

  • ANT+ compatible
  • Crankset is compatible with both standard and compact rings.

Still the best - The Standard

  • Familiarity: I've put it through the wringer

It is very hard to make the case of spending nearly $1,000 more on an SRM, than a Quarq, Pioneer, Powertap, or any of the other rapidly accumulating options on the market. I even have a hard to explaining why or how SRM makes a better product; they do!

The best way that I can describe this is if you want to be able to install your power meter and never have to worry about it functioning through your next ride; SRM is the solution. There is a reason why the best cyclisits in the world insist on SRM; because it is the solution that is guaranteed to work all day, everyday, and to do so flawlessly. Simply put, this is the professional solution.

Add the performance of SRM with Shimano's crank arms, and the flawless shifting of their chainrings, and you have the best possible power meter that money can buy.

If you have any questions, feel free to get in touch with me directly.
