    Tuned to take whatever trail you desire.

    We've all got multiple cycling lives, ranging from racing road and 'cross to riding charity sportives and all the long training miles that go into preparing for them. Few cranks can comfortably straddle every aspect of the mutable cyclist's life like Shimano's Ultegra 6800 Crankset, which brings the stiff Hollowtech II design of Dura-Ace to a price that appeals to riders outside of the peloton. The Ultegra 6800 Crankset may not be as light as the Dura-Ace model, but it still checks-in at a race-worthy 765g.

    While the Ultegra 6800 drivetrain's two extra speeds may be the most noticeable upgrade, in truth, the entire crankset has been redesigned to follow in its big brother’s footsteps. The biggest change is the use of a four-arm, rather than the traditional five-arm, spider, which saves a claimed 26g. The new crankset design also standardizes the bolt circle diameter, so it accommodates standard or compact chainrings without having to spring for a completely new crankset. You’re able to switch gearing from a 55-42t down to a 46-36t in a matter of a few minutes.

    • The crankset favored by privateer racers
    • Hollow aluminum construction based on Dura-Ace model
    • Ring sizes can be swapped without changing spiders
    • 4-arm spider accommodates chainring sizes from 46-36t to 55-42t
    • Compatible with Shimano 6800, 11-speed shifters and chainrings
    • Item #SHI0656

    Good Looking Road Crank

    • Familiarity: I've used it several times

    This is a good crankset. It looks great and is well designed. I wish it offered the option for slightly lower gearing for gravel riding and it would be nice if Shimano kept the same BCD as in the past for more chainring options but for most riders these are perfect.

    Shimano Quality

    • Familiarity: I've put it through the wringer

    What more is there to say about Shimano? Ultegra is simply good. It's reliable, it's quiet, it works. Not everyone loves the look, but few bike parts look "traditional" these days. If you don't mind the extra grams, go for this over Dura-Ace. Less bling, but then again, I like to fly under the radar.

    Flawless function

    • Familiarity: I've used it several times

    I bought this crankset because I wanted shorter crankarms for my cyclocross bike. The rest of the drivetrain is SRAM Force or Red 10-speed, but the Ultegra 11-speed rings (46T/36T) shift perfectly.
    Installation is a snap; if you're new to Shimano's Hollowtech design, don't go crazy with the preload widget, and follow the torque specs for the non-driveside crankarm bolts.
    I only have a few hours of ride time on this crankset, but if it's like any other Shimano products I've owned, I expect it to provide trouble-free use for a long time.

    No complaints at all!

    • Familiarity: I've put it through the wringer

    I use this crank on my racing bike, so I've thrown a lot at it. I'm not so much concerned about the weight--which is light enough--more important is the shifting performance. As part of the Ultegra system, the shifting is really good and I don't have problems with dropped chains. Having Ultegra won't make you 10 watts faster, but it matters having shifting you can trust in a high pressure situation. I take care to maintain my chain (with Molten Speed wax) and so the teeth on the rings have survived two racing seasons and still look great.

    I also like the Hollowtech system, which makes removal and maintenance very easy--you just need an allen wrench. I once had Campy Centaur and unless you had specialized tools you had to take it into the shop to remove.

    Ultegra is not bling-y or fearsome looking, instead it's rather subdued or stealthy, as the picture suggests.

    My go-to crankset...

    • Familiarity: I've put it through the wringer

    I use these on multiple bikes in different configurations. I even use them for my 1x11 cross bike set-up. I like that they are stiff and light enough for the price. You can pay a lot more to get something lighter and possibly stiffer but these are a great higher end crank in comparison. My one gripe would be that they show any imperfections like they are neon.


    • Familiarity: I've put it through the wringer

    I use the 50/34 (compact) in the mountains around Salt Lake City. I'm a big dude (210 lbs) and it handles the abuse. The dark grey color makes any bike look good.


    • Familiarity: I've put it through the wringer

    It is hard to beat the reliability, quality, and acceptable weights that are offered by Shimano's Ultegra group. These cranks are plenty stiff for most riders and offer excellent shifting.
    For the money, you really cannot do better than the Ultegra cranks.

    An Excellent Piece of the Puzzle

    • Familiarity: I've used it several times

    While Ultegra 6800 is very much the sum of its parts, this crankset ends up playing a notable role in the overall performance.

    While it may lack the shiny Dura-Ace looks and packs a few more grams, this is really is a top-tier crank. Construction delivers the level of polish you expect from anything carrying the Shimano name.

    Paired with the Di2 front derailleur I have found the shifts to be fast and reliable no matter the situation. The shift up to the big ring is particularly impressive and at times so immediate I question whether the shift happened at all.


    • Familiarity: I've put it through the wringer

    A definite improvement over the previous model in that the shift from the smaller chainring to the larger one is extremely smooth; it's almost as if you have to look down at the chainwheel to see if the shift occurred. More durable but heavier then the dura ace, but at a much more affordable price. No flex in the crank arm, stiff and smooth.

    crank arm broke off

    • Familiarity: I've put it through the wringer

    was using it for about a year and it started bending on the weld part where crank arm is connected and just snapped right off on a climb standing. got dura ace instead.happy for now

    Ultra Hollow Crankset

    • Familiarity: I've used it several times

    Last winter, I totaled my 7 year old S-Works Roubaix, and miraculously, it was covered by my homeowners' insurance. I had my local shop build a new bike on a current S-Works SL4 frame, using Dura-Ace Di2, but I used the Ultegra crankset because I just though it looked cooler. I've had no problems with it.
    Last week, my stepson salvaged what we could from the wrecked S-Works Roubaix and built a bike for my son using my son's old steel LeMond Buenos Aires frame. Once again, we used an Ultegra compact crankset (the carbon cranks from the wrecked S-Works wouldn't work), and we were surprised to see that the tool that tightens the crankset to the English threaded bottom bracket (cheap piece of plastic) wasn't included in the retail packaging for the crankset. I can understand why shops would have this tool at their disposal, but I cannot imagine any reason not to include it in the retail packaging.

    Other than that one little gripe, I'm very pleased.

    Unanswered Question

    What bottom bracket is this crank designed for? Is this crank for an english threaded bottom bracket, and is this bottom bracket included?

    Unanswered Question

    I have a FSA Gossamer BB30 crank on my Specialized Secteur. Will I need any type of conversion kit for this crank or will it fit without any alterations?

    Unanswered Question

    I have an old Trek 5200 with a FC-6503 crankset and BB-6500 bottom bracket. I'd like to upgrade to Ultegra 6800 components but not sure what I need to do with the BB. Any advice? Thanks!

    Unanswered Question

    I'd like to upgrade my mixed Shimano 9 spd drivetrain (ultegra 9spd brifters, 105 9spd front/rear derailleur, 105 5750 10spd compact crankset, ultegra 6500 9spd 12-27 cassette, and LX HG73 9spd chain) to full Ultegra 6800 drivetrain. Due to cost, I'd like to do this in stages, understanding shifters/derailleurs/cassette/chain will need to be done together, at minimum. Question is, can I upgrade crankset to Ultegra 6800 11 spd 52x36 and run as is until I can get remainder of components?

    Hello, I have a road bike with a 10-speed Shimano 105 group and want to upgrade some parts to the new 11-speed Shimano. Are the groups compatible, will this 11-speed crankset work with 10-speed components? Thanks

    Unanswered Question

    Any issues putting this on a QR Kilo currently running FSA Omega crankset / MEGA EXO BB? Also running 10-spd SRAM Rival. Any issues with 10 speed? Thanks!

    My road bike is Ultegra Di 10 spd equipped but the crank is a rebranded SRAM APEX crank. I would like to swap it out with an ultegra 6800 compact 50/34. Will this work? Do I need a new BB as well?

    While we have not tested it here, there are reports that you will be fine running 6800 11 speed cranks with the 10 speed group. You will indeed to get a new shimano based bottom bracket. Call me at extension 4769 if you have any questions.

    Have found out that ultegra 6750 is still available. That is the 10 sp compact crank. 11 speed cranks are designed for a narrower chain.

    A larger chain will work in the 11 sp crank but it may be noisy.

    I currently use 105 and wants to upgrade to Ultegra 6800. My Tarmac uses BB30, will I have any issues?

    Best Answer

    If you currently have a 105 crank on there, you already have some type of adapter to go from BB30 to Shimano's 24mm spindle. All Shimano spindles are the same diameter, so you'll be fine. Just take the old one off, put this one on, and you'll be good. Remember you'll need the special tool that fits into the black plastic cap that is on the non drive side to loosen and tighten the crank.

    Unanswered Question

    Would this work with my bike (without upgrading other components) if I currently have a triple ring 52/42/30T with a 9 speed cassette. I have a front derailleur shimano sora FD-3403 9 speed, and a rear derailleur tiagra for 9 speed.

    I suppose I'm worried about it being compatible with my front derailleur and shifter... Common sense would say that I would need to change them, but I just wanted to check.

    I have a 10 speed cassette and Ultegra FC-6750 50/34 compact crank, can I upgrade to the FC-6800 52/36 11 speed crank without having to make any other upgrades.

    Yes you can use your existing ten speed chain and cassette with the new 11 speed crankset and chainrings. The outer width of the 11 speed chain isn't very different from the 10 speed and of course the pitch of all bicycle chains is 1/2". Feel free to contact me at if you have any other questions.


    Is the English threaded bb and the installation tool included? I'm guessing No, since you don't ask the buyer to select English v Italian thread...

    Please confirm though

    I have just ordered a Jamis Renegade Elite which comes with a mid-compact 6800 52/36 crankset and the bottom bracket is an FSA PressFit 30 with Wheels MFG adaptors. I have just ordered the 6800 46/36 crankset from you and am curious if I need anything else to run this crankset with this BB setup?
