Product Details

Your front derailleur is the gateway to half of the gears on your bike, and its ability to shift swiftly, accurately, and in a measured fashion can be the difference between a personal best or a dropped chain and oily hand. With the Shimano Ultegra R8000 2 x 11-Speed Front Derailleur, Braze-On, you can be sure of the greatest level of precision possible, and shift seamlessly across your chainset.

With an improved link construction that accurately mimics the force curve of the hand action during the gear shift, you can be sure of a smooth swinging action across the chainset, providing that measured and precise movement that you need to engage and drive onwards. Compatible with chainsets with a top-end range of 46-53T, this front derailleur is a braze-on, assuring you of a rigid and stable base.

A lighter shifting operation making this an easier prospect when flicking to the big ring, the new link construction also allows for a more flexible cable routeing design, allowing you the ability to adjust your tensions manually with ease, and without purpose-made tools.

Q & A

3 questions answered

  1. Will this work with my 6800 crankset (34/50) and  6800 shifters. My intention is to purchase the rear 8000 derailleur as well. 

    Asked by Mad Mike (Surrey)

    1. Hi Mike, Yes this will work no issues at all, Many thanks Joe W

  2. Hi, Is it possible to change Shimano FD 5800 F to Shimano Ultegra R8000 Double 11-Speed Front Derailleur, Braze-On?

    Asked by Sergio66 (Moscow, Russia)

    1. Hello, This would work, however, you would also require the latest chainset, as the shift distance has changed on the R8000 groupset. Many Thanks Liam

  3. Hi Presently I have a shimano 6800 front derailleur/ brifters etc on 11 speed trek domane. Can you confirm the R8000 front derailleur is 'backwards' compatible with the 6800 shifters and 6800 rear derailleur.

    Asked by Roger (South West London)

    1. Hi Roger, Yes this will work with your existing levers no issues at all, Many thanks Joe W

About Shimano

Shifting the way the world rides.

From a single Osaka workshop in 1921, Shimano has grown into the world's most influential component maker. The brand's relentless engineering — Dura-Ace, Ultegra, GRX, XTR — has shaped the way the world shifts, brakes and rides, on the road and off it.

Shimano's flagship groupset, Dura-Ace, has been the benchmark for top-level road components for more than five decades. Every refinement that lands on Dura-Ace eventually shapes the entire Shimano range, all the way down to entry-level drivetrains.
