INTERBIKE 2009 – SRAM introduced two new Wireless power meter cranksets at Interbike, one geared for normal road riding and one single big ring for time trial bikes.
Both are built around Red-level crank arms and rings, but the spider is replaced with the power measurement device. Depending on the model, you’ll get either a Quarq or SRM spider, but both work on the ANT+ system and will work with a variety of receivers and computers.

While SRAM showed a prototype of this at Sea Otter, they waited to introduce it until the units could meet European CEN standards
The double road ring uses an SRM power meter spider built with SRAM’s standard 53/39 Red rings, but you can interchange with any of SRAM’s road rings.
The crank arms on both are UD (uni-directional) carbon fiber, and both models will be available in four arm lengths ranging from 170mm to 177.5mm. They’ll be available in BB30 or standard GXP bottom bracket varieties.
The TT version comes with Quarq’s power meter spider and a nearly solid big ring for puttin’ the hammer down.
Both versions should work with Garmin’s new ANT+ computers, too. They’ll be available in October, and they’ve been raced under Astana, Milram, Michellie Jones and Norman Stadtler during development.
