Model ID FC-FRC-D2 Features Technology Specifications Features X-Range gearing technology gives you more range and a smoother gear progression, so you’re always in the right gear Crisp and accurate front shifts Carbon fiber crankarms for light weight and stiffness Unique chainring shape results in a lighter weight, stiffer, more durable crankset DUB bottom bracket adds durability and simplicity 50/37T, 48/35T and 46/33T chainring combos available Can be upgraded to a power meter Technology 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 progression, as well as smarter shift settings—enabled by AXS. With X-Range, you’re always in the right gear.
