SRAM Red 22 BB30 53 39T 11 Speed Crankset. The SRAM Red 22 BB30 11 speed crankset takes all the innovative breakthroughs that SRAM has had over the years and condenses them down into the lightest, stiffest crankset they've ever made. There's some contradictory thinking at work in the Red 22 crankset but the end result is second to none. To make it stiffer, they used less material. To make it lighter, they made it bigger. By utilizing the properties of carbon fiber SRAM crafted a crankset that is hollow through the arms all the way into the spider. This large hollow cross section makes the crank lighter and also maximizes the stiffness, so you get improved power transfer and shave precious grams from your bike's weight. SRAM also rearranged the bolt patterns to better leverage the characteristics of carbon fiber and make the spider stiffer and lighter. The Glide R chainrings are some of the stiffest on the market, and have been made thinner to accommodate an 11 speed chain. The crankset is optimized for use with the Yaw 22 front derailleur to allow you to execute crisper, more accurate shifting.
