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 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.
Will this front mech work with a RD5800 shifter (105).
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 email@example.com.
Thanks so much!
