SHIMANO Ultegra Fc-R8000 Crankset Gray, 165X50/34 | BCD, Hollowtech II Spindle Interface, Black($365.00Value)

Description

Hollowtech hollow forged crank arms not only the bike's weight, but decreases rotating mass to aid in acceleration Constructed with Hollowglide technology, this 50/34T double chainring setup ensures precise, smooth shifting and increased durability, making it ideal for competitive road cycling and endurance rides. Designed with an innovative 110mm asymmetric BCD and 43.5mm chainline, the crankset offers optimal chain alignment on modern road bikes, enhancing efficiency across varied gear ratios and terrain. Built for versatility and style, the black finish complements a wide range of road bike frames, with compatibility for HG-EV and HG-X11 chains, ensuring seamless integration with your existing drivetrain components. Engineered with 's renowned Hollowtech II spindle interface, this crankset delivers exceptional stiffness and strength, supporting powerful pedaling performance and reliable durability over long-distance rides. Shimano's Ultegra FC-R8000 Crankset represents true trickle down from Shimano's flagship Dura-Ace group not only visually, but in the technological features that make both cranksets light, stiff, and shift with precision. The new, aggressively angular lines increase stiffness, providing excellent power transfer. The chainrings and bolts were also redesigned to provide better chainstay clearance for shorter rear end bikes or road disc bikes with wider dropout spacing. Shimano has the technical expertise and manufacturing prowess to create industry-leading shifting and stiffness to weight for the rings and crank arms, respectively. The latter property is owed to Shimano's Hollowtech II arm construction, a heavily guarded secret. Where other manufacturers drill the arms to reduce weight or create two sides and clam-shell them together, Shimano is able to forge the arms and still keep them hollow. As with the Dura-Ace 9100 series, Shimano adds some width to the R8000's arms and orients the spider to more efficiently transfer energy during important power phases throughout the pedal stroke. The asymmetric spider and chainring spacing allows Shimano to put two chainring bolts close to the wider arms, further adding rigidity to the rings for better shifting and power transfer. As noted above, Shimano's excellent chainring engineering continues with the FC-R8000. We once heard a rumor that Shimano owns patents on every single chainring tooth's shape, pin, shift ramp, etc. We're not sure if this is true, but we do know that, compared to other rings we've used, Shimano rings in operation tend to run much quieter, wear at a much better rate, and offer more positive and quicker shifting. The tooth profiles on this crank have been slightly altered to improve shifting and chain retention at the extreme chainlines seen on the shorter stays of newer bikes combined with larger cassette ranges and wider rear spacing. To lessen the chainline, the inner chainring has been brought...
