Shimano Ultegra FC-R8000 165mm Crankarm Set for Road Bike – Compact 52/36t Chainring

Product Description:

The Shimano Ultegra Hollow Tech II Crankset is engineered for road cyclists seeking a seamless blend of power transfer and lightweight performance. Designed to meet the demands of serious riders, this crankset combines aerodynamic efficiency with rugged durability, making it ideal for high-intensity sprints, grueling climbs, or long-distance endurance rides. Its hollow forged aluminum construction ensures minimal weight—just 681 grams—while maintaining exceptional stiffness for responsive pedaling under pressure.

Whether you’re racing on competitive circuits or tackling varied terrain on your daily commute, the Ultegra’s 52/36T chainring configuration delivers a wide gear range to conquer any challenge. The Shimano Asymmetric 110 BCD design enhances chain stability by increasing clearance between the chain and teeth, reducing friction and wear even during aggressive shifts. This feature also improves compatibility with modern disc brake road bikes, ensuring smooth operation across setups with 130mm hubs or road disc hubs (135/142mm) paired with chainstays over 415mm.

Perfect for riders prioritizing precision and speed, the crankset supports 11-speed drivetrains and is built for seamless integration with Shimano Hollowtech II compatible bottom brackets (sold separately). Its 165mm crank length suits riders with shorter inseams or those favoring agile handling, while the 9/16″ spindle interface offers reliable pedal attachment for consistent power delivery.
