New compact road powermeters from SRM

Plus 2x10 mountain bike option in pipeline

SRM have announced the addition of several new products to their comprehensive range of crank-based powermeters, including options for Dura-Ace 7900, Rotor and 2x10 mountain bike chainsets.

The German company already have a Dura-Ace 7900-compatible version of their popular PowerMeter but have now added a model to work with the range's compact chainrings. The new SRM PowerMeter Dura-Ace 7950 Compatible meter will continue to use previous-generation Dura-Ace 7800 hollow-forged aluminum arms joined to SRM's own spider with sculpted arms to blend seamlessly with the extra-deep hollow forged chainrings. 

In addition to the new size, the 7950 version will also feature a laser etched SRM logo in place of the current decal for a more upscale appearance to go along with the system's US$4,095 asking price ($3,145 without the computer head).

Rotor-based powermeters are now also available according to SRM, featuring the company's clever drilled-out aluminum crankarms as used by Garmin-Cervélo. SRM will offer Rotor-based powermeters in both 3D and 3D+ versions (the latter meant for use with BBright or 386 Evo bottom bracket standards), and current Rotor 3D or 3D+ owners can send their cranks in to SRM for retrofit.

SRM also say their latest 2x10-compatible mountain bike powermeters are undergoing the beta test phase and will soon be available to work with current transmission offerings from SRAM and Shimano.

James started as a roadie in 1990 with his high school team but switched to dirt in 1994 and has enjoyed both ever since. Anything that comes through his hands is bound to be taken apart, and those hands still sometimes smell like fork oil even though he retired from shop life in 2007. He prefers manual over automatic, fizzy over still, and the right way over the easy way.
  • Discipline: Mountain, road, cyclocross
  • Preferred Terrain: Up in the Colorado high-country where the singletrack is still single, the dirt is still brown, and the aspens are in full bloom. Also, those perfect stretches of pavement where the road snakes across the mountainside like an artist's paintbrush.
  • Beer of Choice: Mexican Coke
  • Location: Boulder, Colorado, USA
