Technologies
DUB
The relationship between bottom bracket spindle and bearing is the core of DUB technology. Its where stiffness meets durability. We took it a step beyond conventional thinking and made everything simplerbetter integrating the relationship between chainring, crank, spindle, and bottom bracket. Its this approach to developing a complete system that equals better drivetrain performance.
Carbon Tuned
Strength and stiffness where you need it, lightweight like you want it. Proprietary 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.
X-Range
Road bikes are faster and more capable than ever before, and riders are expanding whats possible with drop bar bikes. X-Range is gearing for todays road riding. SRAM completely reimagined road gearing for wider range, more useful and smoother gear progression, as well as smarter shift settingsenabled by AXS. With X-Range, youre always in the right gear.
