TECHNOLOGIES

DUB - The relationship between bottom bracket spindle and bearing is the core of DUB technology. It's where stiffness meets durability. We 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. We completely reimagined road gearing for wider range, more useful and smoother gear progresion, as well as smarter shift settings - enabled by AXS. With X-Range, you're always in the right gear.
