Rated 5 out of 5 by Brought for HILLS I was entered into this years etape, i'm not the smallest cyclist and needed more gears as big hills, this with 12-30 cassette has worked for me, i've been in Spain doing training up cat 1 climbs for over 2 hours of climbing and it was hard but plodded along. I'm now looking forward to the Etape. 11 June 2014
Rated 5 out of 5 by Great upgrade Upgrading my 10/double Tiagra gear , easy to fit and set up and works really smoothly. 24 May 2014
Rated 5 out of 5 by Quality mech Matched up with ulltegra Sti shifters, this rear mech is superb, very easy to fit, and very little adjustment required, works flawlessly. Highly recommended. 29 April 2014
Rated 5 out of 5 by Nice action After purchasing my Ultegra 12x30 cass. I had to change out my DA 7800 derailluer due to the lack of clearance. I could have possibly made it work but the precision would have been compromised. This 6700 is doing a great job with out the anxiety the 7800 might have caused. The 12x30 coupled with the 6700 is a great team. 23 March 2014
Rated 5 out of 5 by Very good! Ultegra 6700 is quite a sufficient level for training, rear deraileur works fine as well. 01 March 2014
Rated 4 out of 5 by Este es un producto resistente y de calidad Es un buen producto y fiable, pero con los golpes que se sufre en carretera tiende a perder su regulación con relativa frecuencia 09 February 2014
Rated 4 out of 5 by Buon Servizio al Cliente e buoni prezzi Devo dire che, dopo un primo problema legato al colore del cambio ultegra 6700, sono stato assistito bene dalla Sig.ra Angela nel risolvere il problema in tempi brevi. 23 January 2014

Answer: 
Sadly it won't work, you will have gear-shifting issues unless you use a compatible 9-speed rear mech to partner your existing drivetrain.

Answer: 
I answer myself with this cuestion answered before mine:
"I have an Ultegra CS-6700 12/30 cassette and I am looking to use it with an Ultegra RD-6700-A derailleur.
I understand that there are two versions of the RD-6700 derailleur, the original RD-6700 and the RD-6700-A. I understand that the RD-6700 is specified to take a maximum 28T sprocket and 39T total capacity, whereas the RD-6700-A is specified to take a maximum 30T sprocket and 40T total capacity."

And the staff confirmed that (item is RD-6700-A), so it's all I need (yesterday I ordered this item with CS-6700 12/30T)… Thanks.

Answer: 
I run this mech, with a 11/28 cassette, but a compact 50/34 up front, but I would think the only difference would be chain length. It will handle the 11/28 cassette, no problem.

Answer: 
A Shimano road medium cage is 83mm in length from the jockey wheels centre to centre. If your own cage is shorter you will then require a medium cage mech.

It is not possible to switch cages between mech bodies.

Answer: 
This derailleur is for use with a Road drivetrain and a Road cassette; shifting will not be as fluid or as accurate when using a MTB cassette and is not recommended.
