The skeptics among us have been using the same front derailleur since their down tube shifting days; 'they're all the same' they cry when they see that there is yet another iteration of the front mech. Shimano says otherwise; their Ultegra FD-6700 front derailleur is different from the derailleur it's replacing, the 6600, and it is different from the Dura-Ace 7900.

Compared to the 6600, this shape of this unit has been tweaked to minimize the need for trimming the front derailleur, and the spring is lighter for less push necessary at the lever. The shift links have been widened to make the shifter torsionally stiffer. All in all, the shifting will feel smoother, lighter, and more precise. It is different from 7900 in that the cage is wider and designed to work with a front STI shifter that still has an intermediate "trim" shift -- Dura-Ace doesn't have this feature anymore. Shimano says this front derailleur will work with older 6600 shifters, but considers it 'B' compatible -- it works, but not great.

This Ultegra FD-6700 front derailleur is designed for compact (110mm bolt circle diameter) and standard (130mm bcd) double cranksets. There are three different versions -- braze-on, 34.9mm clamp, and 31.8/28.6mm clamp (which comes with a shim to reduce the diameter from the larger size to the smaller). It can handle a big/small ring differential of up to 16 teeth (as in up to 34/50).

  • Wide Pivot Link design inhibits flex for better shifts
  • Braze-on fits frames with pre-existing front derailleur braze-on mount
  • Can also be used with braze-on clamp adapters
  • SG-X Chainring compatible
  • Compatible with older 6600 10-speed systems

Moving my 6600 groupset from one bike to another. The FD clamp size is different so doesn't fit. Seems to have better luck finding 6700 front derailleur price and availability. Will that work with my 6600 double shifters?

hello there i have 2005 trek 820 series can i used this?
Front Derailleur Shimano FD-C051
Rear Cogs 7-speed, 13 - 34 teeth

Isn't the 820 a mountain bike with a triple chainring? This derailleur may not have the capacity for a triple. I also think it is overkill for this bike.

I have a Cannondale CAAD 9 2010. I've upgraded the rear with the Ultegra 6700 11-28 Cassete and Derailleur. I'm now going to upgrade the Crank (double) with an 6700. What size 6700 Derailleur will be right for my application? I see two sizes mentioned (34.9mm and 31.8mm/2806mm band).The derailleur I need is a bracket design. Thank you in advance for your help.

Nice bike man. The CAAD 9s use a 34.9mm clamp on derailleur. Enjoy the ride.

I have a 28.6 downtube. I see that this product offers a 31.8/2806mm is this a mistype? Or is my only option dura-ace? Can a 31.8 in Sram work if not does Sram offer a 28.6?

The 31.8/28.6 will work with either and their should be plastic clamp adapters included to make it fit the 28.6.

can i use this Shimano Ultegra FD-6700 Front Derailleur with a 7 speed

No this derailleur is compatible with 10-speed Shimano cassettes and chains. If for a road bike you are going to want to look for Shimano Tourney FD-C050 'top pull' or FD-C051 'bottom pull or Shimano Altus derailleur, they are about $30. In this case I would recommend contacting your local bike shop.
