Shimano Ultegra 6800 11 Speed Front Derailleur

Shimano Ultegra 6800 11-Speed is one of the most anticipated groupos of the season. With trickle down from Dura-Ace 9000, what’s not to love? This race inspired group is super fast, reliable, and above all… smooth. The 6800 front derailleur have received a revised actuation ratio which means that it’ll be easier to shift up the to the big ring and faster. In addition, a new support bolt has been added for added support on for the braze on edition.

  • Improved Actuation Ratio
  • Added Bolt for Stability in the Braze-On Edition
  • Super Smooth
  • Trickle Down technology from Dura-Ace

Comments about Shimano Ultegra FD-6800 Front Derailleur:

Shimano's new "long arm" design clearly was never tested on a cyclocross bike. 20 years ago I expected that lack of consideration when 'cross was still a fringe activity. Now that cyclocross is nearly mainstream I'd expect Shimano to pay more attention to component usage on 'cross frame.

Functionally, I don't feel any improvement shifting the 6800 derailleur over the 6700 and earlier models with "short" swing arms. But given the other difficulties and narrow compatibility of 11-speed components I opted to use matched components rather than a more traditional "Frankbike" approach to my 'cross build. Setup is tedious and you MUST FOLLOW THE INSTRUCTIONS to achieve proper installation. The 11-speed 2X crankset shifting works correctly when installed and tuned according to Shimano instructions.

Fit is the problem. The long swing arm moves deep into the rear wheel well behind the seat tube when shifting to the large ring. My Soma frame with 425mm chainstays easily accommodates 700x40 tires with a "short arm" 6700 derailleur. This 6800 version HITS THE TIRE when using 40 width rubber. I had to down size to 700x35 tires just to accommodate this derailleur. 35 is tight but there is still a small gap between the tread and the derailleur cable fixing bolt. I have never had to switch tires to accommodate a derailleur in my entire lifetime of cycling.

My personal feeling is that this "long arm" design is a complete failure as it impedes on the tire clearance so significantly. I only use a 'cross bike for road riding these days. But my suspicion is that a road frame with shorter chainstays would run into similar tire clearance issues even trying to use moderately chubby road slicks.

      With Ultegra 50/34 Compact Crankset. Works well and I like the intra-shift trim options available. I'm using this with the Shimano RS 700 rapid fire shifter for use with flat bars.

      Comments about Shimano Ultegra FD-6800 Front Derailleur:

      Compared to the Shimano XT and Alivio on my other bikes this thing is much smoother and quick. Honestly not easy to dial in but once it's right it's flawless.

          Comments about Shimano Ultegra FD-6800 Front Derailleur:

          I love the Shimano 11sp derailleurs, as they're better derailleurs than anything else I've tried once set up. But... these 11 speed Shimano Front derailleurs are finicky! You need some serious finagling to get it to function optimally. Do NOT use these on a frame with a clamp-style braze-on adaptor, only those with built-on braze ons. The reasoning is that it's very hard to get it aligned properly, as the leverage is very picky on these. If you need a clamp-on style derailleur, use the clamp-on variant of this derailleur. The difference between this derailleur and Dura-Ace is pretty minimal, you won't gain much going with the higher-end one.

          Comments about Shimano Ultegra FD-6800 Front Derailleur:

          If you've ever interacted with me on a bike level, you probably realized moderately quickly that I only have loyalty to brands as long as they earn it. I have long loved the lifelong reliability of my Shimano drivetrains, but I personally did not love the feel of the shifts. This is very much a preference, and not a fact. However, it was this that had me make the brand switch not too many years back.

          Well, Shimano may have just swung my opinions back with the new 105, Ultegra, and Dura Ace 11-spd groups. The new groups shift so incredibly fast that I was stunned. I am a fan of the quick precision shifting of Di2, but when I jumped on the new Ultegra group I felt that it may be equally fast, if not faster.

          The front derailleur blew me away the most. There was never a hesitation as I jumped from one ring to the other. It felt instantaneous.

          I will probably always buy the Ultegra group from Shimano because it carries so many of the great qualities of Dura-Ace without the price tag. For me it's the perfect go-to group unless you need the absolute top-of-the-line.

          My only gripe with the derailleur is that there is a bit more finesse required to get it dialed in, but once there it's next to perfect.

            Is the shimano ultegra FD-6800 Front Derailleur compatible with Shimano 105 shifter? My 105 front derailler is gone and I want to buy a new one. My bike is a Diamond Back Podium Sport 2012, so I have 20 speeds.

            • A:

              It depends what generation 105 you have. For 6800 and 5800, the amount of cable pulled by the sti shifter was changed and the leverage--or the distance the front derailleur cage moves for a given pull--was also changed to make it easier to shift. If you have 5800 105 levers then it will work. If you don't, it will not work at all.
