    Shaped by Dura-Ace.

    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 in .4mm towards the bike, and specially designed chainring bolts ensure enough clearance between them and the chainstays. To optimize front shifting, Shimano recommends the new FD-R8000 front derailleur as it's designed for the new chainrings' placements and allows for proper frame clearance.

    Features that have been on Shimano road cranks for years are still present in this design. A 24mm steel spindle is bonded to the drive side aluminum arm and is compatible with many frame and bottom bracket—ahem—standards. The non-drive arm slides onto the crank axle with splines and allows for a precise fit. The included crank fixing bolt adjusts bearing preload and the pinch bolts secure the arm to the spindle, and the Hollowglide chainrings are lightweight and super stiff. Similar to what Shimano has done on their mountain chainrings, the outer chainring is aluminum and bonded to a composite structure, increasing stiffness while decreasing weight.

    The Ultegra FC-R8000 Crankset is offered in 4 different lengths and chainring combinations, so regardless of your fit or bike's requirements, you are covered. All chainring sizes work on the same proprietary asymmetric 4-arm spider, so changing out chainrings for different terrain, disciplines, or seasons is easy. We're once again blown away by the performance and value Shimano packs into its Ultegra cranksets and feel confident that this crank will serve us well for years with the flexibility to swap it between bikes if needed.

    Awesome Upgrade

    • Familiarity: I've used it several times

    This was an awesome upgrade from my original set. I bought this to improve my training and I couldn't have asked for a better product.

    Ultegra is simply awesome!

    Perfect blend of high-end and cost

    • Familiarity: I've put it through the wringer

    Love the Ultegra groupset. Classy, feels great, light, and significantly cheaper than higher-end builds for marginal weight gains. Very happy with it!

    Great cranks from Shimano, as usual. Was using another crank with my Ultegra 6800’s and decided to upgrade. Works great with the older iteration of Ultegra. The beauty of Shimano! Shifts better and less chain rattle/creek from the chains. Next time, I’m sticking to the group set. Great price and shipping from CC. Long time customer. No cons that I can think of. My 6800 Stages PM fits perfectly on these cranks. The color is a little different though.

    Shimano R8000 Crankset

    • Familiarity: I've used it once or twice and have initial impressions

    I wanted a compact gearing for a bmc road bike that i built and these fit the budget! They are strong and light weight.

    Big improvement

    • Familiarity: I've used it several times

    Recently cracked the chainring on my FC-6800 cranks. The FC-R8000 cranks are noticeably stiffer than the FC-6800. I have this paired with a Wheels Manufacturing BB30. So far so good. Great price from CC Highly recommend.


    • Familiarity: I've put it through the wringer

    light, stiff, great cranks. If you can spend the extra for DA I'd do it, but for the money you can't beat the new ultegra all the way around.

    Can't argue Shimano's quality

    • Familiarity: I've used it several times

    Recently upgraded one of my bikes from Shimano 6800 to the new R8000 group and couldn't be any happier! The upgrades to the cranks, derailleurs, brakes and shifters have made this one worthwhile upgrade. These cranks not only look great, they are sleek and shift incredibly smooth.

    Unanswered Question

    I’m just getting to biking and just bought a used Trek frame with BB90 bottom bracket I was told, and I’m getting all confused on what crankset will fit onto it. Is the ultegra FC R8000 would work with no problem. Thanks


    Unanswered Question

    Will this work with a BB 73 width? replaceing a praxis alba which was the noisiest crank I ever rode. Thanks tim

    are the new dura-ace (FC-R9100) chain rings compatible with ultegra (FC-R8000)? BC doesn't have the ultegra FC-R8000 52-36 chainrings (36T) in stock...

    Unanswered Question

    I know it's listed as 11 speed. Can this be used with a 10 speed cassette?

    Can I replace the chainrings of a 50/34 Ultegra R8000 with a 52/36 or with a 53/39?

    Hey Manuel,

    Thanks for the question!

    Unfortunately you will not be able to replace the individual chain rings but we do sell crank set with both 52/36 and 53/39 gear combinations that you were asking about. If you have any other questions please feel free to contact me directly.

    Do you need a Shimano bottom bracket for compatibility with these cranks?
