SRAM made a thunderous entrance into the road componentry marketplace in 2007 with the introduction of their Force and Rival gruppos. And when they unveiled their ProTour-caliber Red gruppo in 2008, they proved that they have the engineering nous necessary to compete on a Record/Dura-Ace level. SRAM has some serious game.

SRM -- an engineering powerhouse in their own right -- had the forethought to recognize that as more and more riders choose Red and Force components for their bikes, they'd want an SRM powermeter made specifically for their SRAM drivetrains. And that's exactly what you get here -- in essence a modified Force crankset that houses an SRM Professional powermeter. But here's one critical detail: This system is also 100% compatible with any Campagnolo 10-speed or Shimano 10-speed drivetrain. It's not just for bikes equipped with SRAM!

The electronics inside this crankset are identical to what you get in SRM's other Pro-caliber powermeter systems. They have 8 strain gauges and are accurate to within +/- 2%. (The original SRM Pro powermeters had only 4 strain gauges, but the newer generation Pro systems are made from less material which allows more deflection of the material under stress. The extra strain gauges compensate for this.)

The SRAM system comes complete with a PowerControl V, a 31.8mm handlebar clamp, a power/speed sensor, a PowerControl charger, SRMWin software, a USB-based download cable, and all other associated mounting hardware.

This system requires the use of a SRAM GXP external bearing bottom bracket (either the GXP Ceramic or the GXP Team is ideal here.) This bottom bracket must be purchased separately. The crankset is modeled after Force, which means the arms are carbon fiber, and they have the bottom bracket spindle molded into the driveside crankarm. One thing that distinguishes Red cranksets from Force is Red's use of a fully-carbon fiber crank spider. Since the spider here is occupied by a powermeter, it's not carbon.

This system comes equipped with 53/39 chainrings. They're SRAM's Powerglide chainrings, so they're dialed for use with SRAM DoubleTap shifters, SRAM derailleurs, and a SRAM chain and cassette. The beauty of SRAM drivetrains is that their components are interchangeable. It doesn't matter if you're running Red, Force, or Rival -- this system will shift beautifully.

Available in 172.5mm or 175mm crank lengths.
