Power meets precision with the Shimano ULTEGRA R8000 50/34T 172.5mm Crankset—an elite-grade drivetrain component built for cyclists who thrive on performance, efficiency, and every watt of advantage they can gain. At the intersection of road racing technology and rider-focused design, this crankset is a mechanical extension of your intent to ride fast, far, and fearlessly.

Developed with Hollowtech II engineering, the crank arms are hollow-forged from premium aluminum, giving you the rare combination of stiffness, weight savings, and durability. Every pedal stroke is efficiently translated into kinetic power, letting your effort flow into momentum with minimal energy loss. Whether you're grinding up alpine ascents or launching attacks on the flats, the R8000 ensures that your legs get the most out of every revolution.

The 50/34T compact chainrings are fine-tuned for real-world riding. The 50T big ring delivers the punch for sprints, descents, and group rides where speed matters. Drop into the 34T inner ring and suddenly, long climbs become more manageable and your cadence stays fluid. The pairing provides an optimal gear spread for all-around performance—perfect for cyclists who ride with both power and finesse.

The 172.5mm crank arm length is the gold standard for many riders, offering the ideal midpoint between rapid acceleration and sustained cadence. It provides just the right leverage to keep your ride efficient and controlled, especially during tempo climbs and rolling terrain transitions.

True to Shimano’s legacy of innovation, the ULTEGRA R8000 crankset boasts meticulously sculpted chainrings with precise tooth profiling, ensuring flawless, lightning-fast front shifting—even under full load. The chainrings are also designed to work harmoniously with the complete 11-speed ULTEGRA groupset, giving you drivetrain synergy that feels intuitive and responsive.

The finish is stealthy and refined—a matte black aesthetic that seamlessly blends with modern carbon and alloy road bikes. And because this crankset comes in OEM packaging, it’s perfect for those who value substance over frills—professional-grade performance without the flashy box.

The Shimano ULTEGRA R8000 50/34T 172.5mm Crankset isn’t just a component—it’s a commitment to pushing your limits, mile after mile, gear after gear.
