Shimano Ultegra R8100 12 Speed ChainsetThe Ultegra R8100 12 Speed Chainset from Shimano offers efficient power transfer, smooth gear shifting performance and top-quality race-ready reliability. Ideal for competitive road racing, this chainset offers the optimal balance of stiffness and strength at a low weight. Plus, it features Hollowtech II crank arms, a Hollowglide outer chainring and is compatible with most modern bottom bracket standards from Shimano.Shimano's Ultegra FC-R8100 crank maintains the same quick, precise front shifting and efficient power transfer that Shimano riders have grown accustomed to, but with even more crank arm length options. Spanning 160 to 175 mm in length, Ultegra cranks now cater to smaller riders, triathletes, and cyclists curious about shorter crank arms. An integral part of Shimano's new 12-Speed road lineup, the FC-R8100 crank builds upon Shimano's legendary front shifting and transmission efficiency. With new refinements for seamless 12-Speed shifting, the Ultegra crank is now offered in lengths from 160 to 175 mm, bringing performance and improved fit for smaller riders, triathletes, and riders with specific biomechanical requirements. Hollowglide ChainringHollow technology on the outer chainring. The Hollowglide construction ensures high rigidity while its hollow structure cuts down on weight yet maintains strength. This provides better power transfer and quicker and more precise front shifting performance. Hollowtech II Forged Crank ArmsA lightweight crankset not only reduces the bike's weight but decreases rotating mass to aid in acceleration. The challenge is to reduce the weight of the crank without reducing its strength and rigidity. Shimano's advanced forging technology has solved the problem through the HOLLOWTECH crank. Just like high-quality frame tubing, a hollow crank arm can provide amazing strength and rigidity at very lightweight. Optimised Balance of Stiffness, Strength and WeightThe concept of Hollowtech II technology is focused on producing a superior crankset that will maximize a rider's power transfer. The rigidity of the crankset ensures pedalling efficiency while its low weight, a key element of the crankset, aids in cycling longer distances over which the rider needs to pedal more. Naturally, Shimano strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. The addition of Hollowtech II technology integrates the bottom bracket axle with the right crankarm for more stiffness and weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedalling stability, allowing for more efficient power transfer. Features: Material: Hollowtech II Aluminium Series: Ultegra R8100 Series Optimal balance of stiffness, strength, weight and rotational performance HOLLOWGLIDE structure cuts weight yet maintains strength for better power transfer and quicker, more precise front shifting Recommended Bottom Bracket: Press-Fit: SM-BB72-41B; Threaded: SM-BBR60 Q-Factor: 148mm Chainline: 44.5mm Drivetrain Speeds: 12-Speed Weight: 711g (52-36T); 700g (50-34T)A 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Chorus 12x Chainsets New 12x Chorus Ultra-Torque chainset for use with the disc or rim brake groupset. The new Chorus chainset is a true concentrate of technology and versatility. Technically advanced thanks to unidirectional construction technology in carbon fibre, it is directly moulded without any surface coating and has an Ultra-Torque steel axle like the Record chainset. The new 12x cranks are more versatile thanks to the new bolt pcd of 123mm, giving it an extremely solid structure, also ensuring a wider variety of uses. The new smaller bolt circle on the Chorus chainset makes it compatible with 36/52, 34/50 and the brand new 32/48 ratio chainrings. Available in 170mm, 172.5mm and 175mm crank lengths. Technologies: Ultra-Torque axle: In steel Features and Benefits: The Q Factor remains the same (145.5): The widths and biodynamics of the stroke are the same. Unidirectional carbon fibre cranks, steel axle and aluminium chainrings: Good stiffness and optimum power transmission. Symmetrical teeth on the internal chainring: Fluid, precise transmission, even with extreme cross-chaining. Optimised design for any chainring combination: Maximum performance, whatever the course style. Double Fixing: Assembly of the large chainring on to the crank is secured by a ring of 123mm bolts, while the inner chainring is attached to the outer by way of 96mm pcd bolts. Surface treatment of the chainrings for longer life Weight: 718g (172.5 34/50)
