Technologies

DUB

The relationship between the bottom bracket spindle and the bearing is the heart of DUB technology. It’s where stiffness meets durability. Sram has simplified everything by better integrating the relationship between chainring, crank arm, spindle, and bottom bracket. This approach to developing a complete system results in better drivetrain performance.

X-Range

With X-Range, you’re always in the right gear. Road bikes are faster and more capable than ever, and riders are evolving with drop bar bikes. X-Range is the gearing for today’s road riding. Sram has completely reimagined gearing for a wider and more useful range, as well as smarter shifting settings with AXS.
