Rated 4.2 out of 5 by 5 reviewers.
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
Rated 3 out of 5 by It does the job. Not sure it's worth the premium for Ultegra As I said it does the job but I don't think it does it much better than their cheaper models. A common let down is with the shimano adjustment screws. They are soft which allows the slots to be damaged with normal adjusting. I'd like it a lot more if they went to allen screws instead. 17 December 2013

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.

I am looking for a rear derailleur that can handle an 11/34 cassette and a cassette to go with it. I am currently running Dura Ace but would consider Ultegra as an alternative for my Cervelo RS. I have an 11/28 Ultegra cassette but our area contains many climbs that run 15% and steeper and I need some more help to keep spinning.

Answers

Answer: 
This rear mech in its Medium cage form will only deal with a 32 tooth. If you go above a 32tooth cassette you will then need to change the rear mech to a longer cage or MTB style version.
What you can do, which will give you the same ratio is change your 39 tooth chainring to a 34 tooth chainring. This will give the same gearing for better hill climbing.

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: 
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.
