Shimano Ultegra FC-R8000 Crankset – High-Performance 172.5mm Compact Chainring

The Shimano Ultegra Hollow Tech II Crankset is engineered for road cyclists seeking a perfect balance of lightweight performance and unwavering stiffness. Designed to excel in endurance riding and aggressive sprints alike, this crankset combines advanced materials with precision engineering to deliver responsive power transfer without sacrificing agility. Its hollow forged arms reduce weight to just 674g while maintaining rigidity for maximum energy efficiency—ideal for tackling steep climbs or high-speed descents on demanding routes.

Key features include a 50/34T chainring configuration paired with an 11-speed drivetrain, offering wide-ranging gearing versatility for varied terrain. The Shimano Asymmetric BCD 110 design enhances chain retention and reduces wear by increasing clearance between the chain and leading teeth—a critical advantage during high-intensity pedaling or rough road conditions. Compatible with 130mm hubs and disc brake systems (135/142mm hubs with chainstays over 415mm), it seamlessly integrates into modern road builds without compromising geometry or stability.

Built for precision, this double-ring setup pairs with Shimano Hollowtech II spindle technology (9/16″ pedal interface) and a 172.5mm crank length, ensuring smooth power delivery and optimal pedal stroke efficiency. While no bottom bracket is included (allowing customization for existing setups), its sleek black finish and road-specific design make it a standout choice for performance-oriented riders upgrading their drivetrain systems.
