Great product.
As easy to install as any derailleur can be. Replaced a short cage for medium length cage for 30 tooth sprocket.

Just what I've come to expect from Ultegra
I've been using Ultegra parts since 1988. Always reliable. A little too soon to know for sure, but it's working well and I expect I'll be using it for some time to come.

Sweet Spot Rear Derailleur
This derailleur is the sweet spot. Reasonable price but precise, solid, smooth, adjustable, and durable. Currently running it as the shifter in a 1x10 RB setup shifting a 11-28 cassette. As with previous Ultegra 6600, expecting to get ~30,000 miles on this one before transitioning to 11 speed setup.

Super replacement product!
I replaced the OEM 6700 rear derailleur with the updated 6700-A and now have zero issues utilizing the 12-30 rear cassette to it's fullest potential. I did add one link-pair to a new chain however, as the new item is about one centimeter longer in cage length. That said, I can now use ALL gears without fear of any issues, since this item is approved up to 30T and a total of 34T total difference per Shimano. Looks like a WIN-WIN situation.

Works just fine
Used to build up an old Litespeed frame. Shifts very smoothly, and successfully handles up to a 30-tooth rear cog.

is this compatible with 105 shifters?
A shopper on Mar 25, 2017
BEST ANSWER: Yes, I had a road bike with 105 shifters (didn't want to buy the Ultegra shifters at the time) and an Ultegra rear derailleur and they worked fine. I've used 105, Ultegra and Dura-Ace cassettes, and as long as all the components are 10-speed for a road bike, they'll work fine together.
I have a 1993 7speed downturn shifting road bike 105.
I put a used ultegra 9 speed wheel on it but the current derailleur will only use some of the gears.
Will the ultegra 6700 rear derailleur work with this wheel and my downtube tension shifters?
Tim K on May 21, 2017
BEST ANSWER: The Ultegra 6700-A rear derailleur should work Check to see that the derailleur hanger will accept the 6700-A derailleur. The 6700-A derailleur has a longer cage than the 6700 model, so it will work better with larger cogs (lower gears). If only some gears will work, first check the limit screws on your existing derailleur to see that they are not limiting movement of the derailleur. Also check to see if the chain is properly sized. Note that if you do install the 6700-A derailleur, the current number of chain links may need to be changed to get good performance across all gears.
What does it mean mid or short cage and how can you which i have?
Randy P on Jun 27, 2017
BEST ANSWER: It is just a general way of describing the distance between the the 2 pully wheels. The short cage length will work for cassettes with up to 28t. The mid cage length for cassettes with 28 to 32t. If you have a triple crank set, you would need a long cage.
Can i use this to upgrade my current 9 speed ultegra derailleur? And be able to keep 9 speeds.
Julio on Oct 9, 2016
BEST ANSWER: Derailleurs don't care how many speeds you have. 9 speed chain will work fine on ten speed Derailleur.
