The SRAM RED® crankset leverages a pivotal design innovation: smaller chainrings and a wider cassette range.

This leads to smoother and faster shifting up front and more useful gearing for today’s riders. The new configurations improve cadence and efficiency while also delivering shifts that are crisp, clean and quick—every time.

Technologies

Carbon Tuned - Strength and stiffness where you need it, lightweight like you want it. Propreitary SRAM carbon lay-up design increases thickness and stiffness at critical stress areas. Tapered, terraced, carbon architecture ensures the greatest weight savings without compromising strength.

DUB - The relationship between bottom bracket spindle and bearing is the core of DUB technology. It's where stiffness meets durability. They took it a step beyond conventional thinking and made everything simpler- better integrating the relationship between chainring, crank, spindle and bottom bracket. It's this approach to developing a complete system that equals better drivetrain performance.

X-Range - Road bikes are faster and more capable than ever before, and riders are expanding what's possible with drop bar bikes. X-Range is gearing for today's road riding. They completely reimagined road gearing for wider range, more useful and smoother gear progression, as well as smarter shift setting- enable by AXS. With X-Range, you're always in the right gear.
