The BB30 system continues its reign over the peloton as a preferred bottom bracket standard. It's not hard to see why, as an oversized, 30mm spindle and large bottom bracket shell add torsional stiffness, providing a responsive and efficient pedaling platform without increased weight. The system's direct fit, press-in bearings also eliminate the need for aluminum bottom bracket cups, further reducing weight. With the technology licensed from Cannondale more than a decade ago, a multitude of manufacturers now produce BB30-compatible products. SRAM's right there leading the bunch, having engineered its new Red 22 Crankset with the BB30 standard, 'True 22' X Glide R chainring calibration, and innovative Exogram technology. 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 Crankset directly correlate to improved shifting. The new SRAM Red 22 BB30 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 the 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 w...
