Shimano Ultegra Fc-r8100 2x12s

SHIMANO Ultegra FC-R8100 12-Speed CranksetExperience the perfect synthesis of performance, efficiency, and reliability with the SHIMANO Ultegra FC-R8100 2x12s crankset. As a central component for modern road cycling drivetrains, this crankset brings race-proven technology to the dedicated cyclist who demands precision and speed without compromise. The FC-R8100 is engineered to be the heart of your bike´s drivetrain, ensuring every watt of power you produce is translated directly into forward motion.The design philosophy behind the Ultegra R8100 series is centered on achieving the optimal balance of stiffness, strength, light weight, and rotational performance. This crankset is a masterclass in engineering, providing the rigidity needed for explosive sprints and challenging climbs, while remaining lightweight for superior agility and efficiency over long distances. This specific model is part of the core component sets and comes without integrated power sensors, making it the ideal choice for riders who prioritize pure mechanical performance or utilize a separate power measurement system.One of the standout innovations is the HOLLOWGLIDE chainring structure. This advanced construction significantly cuts weight from the outer chainring without sacrificing its structural integrity. The result is not only a lighter crankset but also a marked improvement in front shifting performance. Shifts are quicker, more precise, and incredibly smooth, even under high pedaling load, allowing you to maintain your rhythm and focus on the road ahead. Paired with SHIMANO´s HOLLOWTECH II technology, which integrates the bottom bracket axle with the right crankarm for more stiffness and weight savings, the FC-R8100 sets a new standard for power transfer in its class.Features:* Achieves an optimal balance of stiffness, strength, weight, and rotational performance for an elite riding experience.* HOLLOWTECH II crank arm construction provides a lightweight design without compromising on stiffness.* The HOLLOWGLIDE structure cuts weight from the large chainring yet maintains strength for better power transfer and quicker, more precise front shifting.* Refined gear tooth shaping provides excellent chain engagement and retention, purpose-built for the demands of 12-speed road cycling systems.* Clean and iconic aesthetic that complements any high-performance road bike frame.Specifications:* Series: ULTEGRA R8100* Application: Road Cycling* Type: Without Power Sensors* Crank Arm Length: 165 mm* Gear Combination: 46-36T* Gearing: 2x12-speed* Q-factor: 148 mm* Chain Line: 44.5 mm* Compatible Chain: SHIMANO 12-speed HG* Compatible Bottom Bracket Type: Outboard* Recommended Bottom Bracket (Press-Fit): SM-BB72-41B* Recommended Bottom Bracket (Threaded): SM-BBR60
