Redesigning their Ultegra groupset to bring the pro-proven performance of the Dura Ace 9100 series to a more affordable price, the Shimano Ultegra FD-R8000-B Front Derailleur provides the features of the 9100 groupset with only a marginal gain in weight. Perhaps the biggest improvement is the R9100's new Link construction, that matches the force curve of the hand more naturally, reducing the effort required for shifting while simultaneously providing a lighter shift action.
Designed with ease of use in mind, the Shimano Ultegra FD-R8000-B Front Derailleur sets up easy, and roadside maintenance can now be done without any specialized tools thanks to integrated cable tension adjustments.
This Ultegra FD-R8000-B Front Derailleur is available in two clamp sizes, either 34.9mm or 31.8mm (with a 28.6mm adapter). If your frame needs a braze-on derailleur, the FD-R8000-F Front Derailleur will be compatible. If you need help deciding what is compatible with your frame, feel free to Contact Us, and we'll be happy to help.
Claimed weight: 106 grams.

I reconfigured the drive on my gravel bike and needed a new front derailleur. This one worked perfectly, as I expected it to. Note that Shimano changed the setup procedure for road front derailleurs some years ago and if you've not updated your technique to the new protocol, your installation will fail. The new procedure is as simple as the old one but provides much crisper, more precise shifting. Shimano has full setup details online. Anyway, yes I'd buy this again and yes, I recommend it to others.
Building a carbon race gravel bike this winter and using the Easton cranks and chainring set up. Due to the narrower Q factor of the Easton set up you use a standard Ultegra front derailleur. Using GRX group set everywhere else. This is an excellent combination as I prefer the narrow Q factor over the wider one on the GRX crank set.
Shimano quality as you would expect and at a fair price.
Simple enough to install and adjust. Just don't rip off the little red tag hanging from the cage when it comes out of the box because it is a very useful part of the install process.
It has been on the bike for a few months and shifts smoothly and reliably.
