Employing the latest technologies from elite DURA-ACE R9100 road components and through its proven System Engineering approach, Shimano’s ULTEGRA R8000 series delivers refined rider ergonomics, increased shifting performance and confident control in all riding conditions. Featuring expanded Rider Tuned gearing configurations, more shifting and braking choices and the power of Shimano’s E-Tube Project customization, ULTEGRA R8000 is designed to meet the specific needs of the broad spectrum of performance road cyclists.
From road racing to mixed-terrain adventures, ULTEGRA R8000 is more versatile than ever before. Available with either Di2 electronic or mechanical shifting, each system is also available in either rim brake or hydraulic disc brake options. Expanded Rider Tuned gearing options—including Shimano’s widest-range new 11-34T performance road cassette—enhance drivetrain versatility. ULTEGRA R8000 also utilizes Shimano’s low-profile SHADOW Rear Derailleur design for optimal shift performance and a sleek appearance. For Di2 shift systems, Shimano’s SYNCHRO and SEMI-SYNCHRO Shift programming continues to open up new possibilities.
FC-8000 Crankset delivers increased efficiency and frame compatibility The FC-R8000 HOLLOWTECH II Crankset receives numerous technologies from Dura-Ace R9100 along with shaping which further enhances ULTEGRA’S 4-arm design. Shimano’s Rider Tuned chainring combinations offer multiple gearing configurations via a singular BCD platform for excellent versatility. With redesigned chainring tooth profiling first introduced for DURA-ACE R9100, the ULTEGRA FC-R8000 Crankset is optimized for the latest disc brake frame designs without the need to increase q-factor.
