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.
