Description

Shift your mindset.

The trickle down of Dura-Ace 9100 technology to Ultegra R8000 11-speed drivetrains continues with the FD-R8000 front derailleur. Shimano redesigned it to have a lighter shift action, increased frame and tire clearance, and to work better with chain lines seen on road bikes with disc brakes and shorter chainstays. Everything we love about the Dura-Ace mechanical front derailleur has carried over to the new Ultegra version.

The derailleurs longer arms, which house the cable anchor bolt and debuted on the Ultegra 6800 and Dura Ace 9000 front derailleurs, allow for a lighter shift as the anchor point gives the cable increased leverage. Word is this design was born when Shimano challenged its engineers to make a mechanical version of Ultegra and Dura-Ace that performed well enough and was still able to hold its own against its electronic siblings, particularly the front derailleurs.

The design worked well, but the industry trend towards wider tires and disc brakes pushed the rear end spacing out to 135 or 142mm. Cable routing was more particular with the longer arm derailleurs. Shimano even sent a guide with each derailleur to gauge which way to run the cable to the anchor bolt, but the evolving rear hub spacing made this an untenable solution. To address this, Shimano engineered a new design that increases the clearance between the front derailleur and rear tire and increases shifting responsiveness with more flexible cable routing. The FD-R8000 also includes a cable tension setting adjustment at the derailleur for a more precise and ease setup.

The more compact design doesn't come at a sacrifice of shift feel. Shimano claims that the new link construction matches the force curve of the hand more naturally to reduce effort at the end of shifting. The shift throw is reduced and the effort required to throw the chain to the big ring, even (or especially) while you're exhausted and trying to bridge up, is reduced.

The FD-R8000 Front Derailleur is constructed from a chrome-plated steel cage, stainless steel hardware and bolts, aluminum inner links and graphene fiber-reinforced outer link. The braze-on bracket is forged and painted aluminum as is the clamp on the band clamp versions.

  • A front derailleur for the self-sponsored racer

  • New linkage reduces lever throw and allows for quicker shifts
  • Accommodates a broader range of cable routing
  • More clearance for frames with bigger tires disc brake chain lines
  • Integrated cable tension adjustment eases set-up and reduces frustration

Unanswered Question

If I have an 11-speed 105 setup, can I just change the derailleur. Or do I need to get an Ultegra brifter too?

Will this work with a 10-speed drive train?

Hi Jeffrey, this is designed to work with Ultegra 8000 components and as such it would most likely not work with your 10 speed hoods.



In short no it would not work.

Upgraded from 105 5800

  • Familiarity: I've used it several times

upgraded my old 105 5800 FD to the new Ultegra 8000 and it is a noticeable difference. The cable path was a little weird to understand at first but once you see a photo of it setup it makes perfect sense. The built in cable tensioner is a nice touch and let me get rid of the inline barrel adjuster I had with my previous front derailleur . No complaints with performance it shifts excellent and faster than I expected the front derailleur to and was surprisingly easy to get dialed in.

Definite improvement over the 6800

    I thought long and hard about getting this upgrade because the 6800 worked so much better than my previous front derailleur (Campy Centaur). I finally pulled the trigger on the R8000, and I think it was worth it. Setup is a bit less intuitive than before, but there are good youtube videos and it really is not that hard. In exchange for there being more steps, you get spot-on perfect cable tension. I never could get it quite right with the 6800, making shifting the kind of adventure I don't like. Helping this is the fact that the barrel adjuster is now a hex screw on the unit, and there are markings showing you exactly how much to tension the cable. Shifting becomes crisp, easy, and predictable without a lot of experimentation. Also a big improvement is the elimination of the long lever arm and the projecting cable above it. My calf was constantly brushing them in the small ring--now the cable end projects behind the unit, and out of the way of anything. Whether the shifting potential in a mechanical sense is better than the 6800, I can't say because I'm pretty sure I never got the install optimized. With the 8000, I know I'm getting all of the potential (barring worn cables or housing).

    I honestly don't know what Shimano could do to improve the front derailleur at this point, unless it be to make it more aero.

    Will this front mech work with a RD5800 shifter (105).

    Hey Barry!



    You can absolutely run 5800 series 105 shifters with this. For future reference, all 11 speed 105 and Ultegra components cross over perfectly! If you, or any other readers have any more questions you can feel free to reach out to me directly at jdraper@backcountry.com.



    Thanks so much!

    A Worthwhile Upgrade

    • Familiarity: I've put it through the wringer

    I upgraded my 105 5800 groupset to the new Ultegra R8000. The weight savings and the improvement in performance made this a worthwhile upgrade. While the new Ultegra FD-R8000 will not save you any weight when coming from 105, the improvement in shifting performance is very noticeable, especially when shifting from the small to the big ring. My only complaint is that I found the initial set-up to be somewhat difficult, but once I got it dialed I was very happy.
    The FD-R8000 weighed 90 grams on my PT digital scale.

    Crisp even when cold

    • 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.
    I have been amazed at the crispness of the shifting performance with the new derailleurs and shifters, and it reminds me of the smoothness of the "older" Dura Ace 7800, but much more refined in how quickly it shifts.
    If you have questions, please feel free to reach out to me.

    Scott - will these be compatible with 7900 D-A?
