Shimano Ultegra R8000 11 Speed Group
Ready for a new 8-piece, 2nd generation Shimano 11-speed group that features measurable and tangible improvements, options for greater gearing range, better frame and tire compatibility for wider rear spacing, shorter chainstays and wider tires, and real performance gains? The Ultegra R8000 11-Speed Group is here. You get to work through and pick your components and get special group pricing, even if you upgrade your bottom bracket, chain or cassette. The process is simple. Just work through the selection menus, and choose your options for this R8000 mechanical shifting, standard rim brake groupset. Learn more about R8000 below, or check our individual item listings for full details. If you have any questions or need assistance with the process, please give us a call at 800.627.6664 and one of our staff of cycling experts will talk you through it.
With a striking look, greater gearing capability, and considerable practical and design influence from Dura-Ace 9100, the much anticipated Ultegra R8000 11-speed groupset is here. Cable actuated shifting and braking with the ST-R8000 STI Dual Control Levers offers more positive shift action and better braking with less effort and a light feel. Shimano cracked the code in R9100 and carried the capability to Ultegra. The improved ergonomics, textured hoods and all important integration with other key components make these the best performing Ultegra Dual Control Levers produced, setting the stage for the group itself.
That integration, plus a re-engineered internal shifter mechanism, is key to the improved overall performance. You will only feel the greatest effects when using the R8000 front and rear derailleurs and dual caliper brakes. The components have been designed together, with subtle mechanical changes from Ultegra 6800, that are keyed by the lever actions. You get the increased (from 10mm to 14mm) brake lever throw adjustment to accommodate your hand size. You still get consistent, quick shifts; but the actions require less force. Most of the materials are shared with Dura-Ace, but Ultegra R8000 uses Shimano's wholly reliable multiple bushing system rather than bearings. Only a sensitive rider can tell the difference, and Ultegra durability is unquestioned.
The front derailleur has been re-engineered for greater efficiency, frame and tire clearance, and improved chainline with the wider spacing found on many of today's bikes. Shimano delivered a whole new design that accommodates a wider gear pitch and rear spacing without sacrificing shifting performance while finding a more flexible cable routing design. The FD-R8000 has an integrated cable tension setting for precise setup and tool-free adjustment. With new physical shifting mechanics, the more complicated, yet compact R8000 design has 8 link bushings with construction features and shift lever integration that matches the natural force curve of the hand during lever throw to reduce effort at the end of the shift.
Again, considering where much of the cycling world is headed, the decision was made to make the 11-speed Ultegra RD-R8000 in both short and mid-cage versions so the design could provide efficiency and ultra-crisp shifting for smaller and larger range cassettes. The GS design can accommodate the new 11-34 CS-HG800 cassette. The R8000 rear derailleurs were also optimized with the R8000 Dual Control Levers for faster, more positive shifting, with less hand effort. The RD-R8000 adopts the same R9100 Shadow compact profile and cable routing from the XTR mountain design. Even in the SS design it has a slightly longer cage than most short cage road versions, allowing it to pair with the cassettes from 11-25 to 11-30. The engineers carried forward the direct mount option used in the mountain bike and R9100 designs. Clearly Shimano see's the movement towards thru-axle rear triangles in road bikes incorporating the direct mount option, which eliminates the B-link assembly and pivot, creating a stouter interface between frame and derailleur that results in superbly crisp shifting.
The new graphic design element of the R8000 Crankset is bold and assertive, which is how most of us like to believe we approach every ride, even when we really just go for a quiet spin. Shimano added width and size to the drive side arm for optimal power and efficiency in the most crucial phase of the pedal stroke. Carrying the structure closer to the chainring mount junction just above the oversized arm, more direct power and overall stiffness is applied to the highest stress point on the crank and ring in the drive power phase. Keep in the mind that the asymmetric spider has the same proprietary BCD as the other 11-speed series cranksets. To create a little more diagonal clearance the inner chainring has been offset .4mm inboard to the center of the bike, and is matched by the greater capability of the set-up with the front derailleur.
A serious increase in power and a more linear brake path define the mechanical improvements of the Shimano Ultegra BR-R8000 Brake Calipers. Visually and practically, the new design is much more angular, and you can see where the engineers favored adding and reducing the lightweight aluminum used. The pivots are larger, and the angles clearly offer some aerodynamic relief in those areas. A stabilizer between the pivots adds strength, but also helps to produce a more linear curve to the braking, which is noticeable to the cyclist through greater predictability.The new R8000 design accommodates tires up 28mm with proper clearance around the crown of the tire. A new lever design moves the closed position in-line with the arch of the caliper, for minor aerodynamic benefit. Though you still get and adjusting knob to increase or decrease cable tension, the resin open/close lever no longer has the graduated indexing.
With the bottom bracket, chain, and cassette, Shimano has not made any substantive engineering changes. Yes, the cassette range options are greater, and with our selection menus for these items, you can potentially upgrade or even choose a down grade with the 105 level cassette. All of these options are designed to work with the R8000 system. Please keep in mind that the bottom bracket selection (including many non-Shimano options) is driven by your frame requirements.
That is R8000 in a nutshell. Again, there are more details on each individual item page, including the pure technical details. To be sure, we have been impressed with Shimano&s approach to development with the R8000 line-up, seemingly carrying more from Dura-Ace than ever before, but still with great Ultegra pricing and long-term durability. This 8-piece groupset is the most cost-effective way to upgrade or outfit a new bike, but if you seek to take a more gradual approach, take a look at our Ultegra R8000 5-Piece Upgrade Kit, or the Ultegra R8000 3-Piece Wide Range Upgrade Kit.
