SRAM's re-introduced Red group in 2012 addressed the specific drivetrain requests of cycling's elite athletes, and the culmination of feedback -- combined with early wins aboard the new drivetrain -- confirmed that the modifications were successful. So, when SRAM's engineers took a hard look at how they could improve the marquee Red groupset, the only improvement they could envision was additional gearing. With Red 22, you receive the proven Red platform, with the addition of 22 overall gears. The Red 22 GXP Crankset carries over SRAM's innovative Exogram technology and combines it with 'True 22' X Glide R chainring calibration, giving you the ultimate in drivetrain power and precision. SRAM's first generation Red crankset used a foam core with a carbon structure wrapped around it to meet SRAM's ambitions for drivetrain performance and weight. While the stiff crank arms offered excellent response under load, one complaint that came from a handful of ProTour riders was that under load the front shifts sometimes lacked sufficient precision and crispness. SRAM's team of R&D experts set out to solve this gripe and the changes you'll find on the Red 22 GXP Crankset directly correlate to improved shifting. The new SRAM Red 22 GXP Crankset has gone away from that first-generation foam-core formula, and now has a significantly beefier arm shape with a true hollow cross section. Because of this larger carbon-optimizing structure, SRAM is able to use less material, effectively reducing weight without negatively affecting stiffness. This also allowed them to rotate the spider to take advantage of the large, flex-fighting crank arm. SRAM chose to stick with the 130mm bolt circle diameter standard, ensuring compatibility with aftermarket chainrings, but they've arranged the spider to position a mounting bolt on the backside of the crank arm. By integrating a mounting location within the existing carbon structure, they're able to reduce weight and deflection from shif...
