A new version doesn't always mean a better version. However, when it came to redesigning the lightest road drivetrain in the world, a new version could only be better. How do you improve on what was already the lightest, most ergonomic and efficient mechanical groupset in the world? By making the standard 53/39 version even lighter, even more ergonomic and even more efficient, that's how. And that's exactly what SRAM did with the new Red Crankset. It features remarkable X Glide R chainrings optimized for use with the YAW Technology found in SRAM's new Red front derailleur. Plus, it's lighter, stronger and stiffer than its predecessor (according to SRAM, the new Red crankset has an even higher stiffness-to-weight ratio than Shimano's Dura-Ace crankset).
