Does what I want
by Bill
Holly Springs, GA

I wanted a lower climbing gear & had to go to shimano to get it. The derailleur is rather straight forward on installation & shifts are crisp & reliable. Very satisfied with it.

What a few years of progress makes between groupsets. Much more predictable shifting.

Bought as a replacement for an older version. Went on easily with supplied cables and shifts smoothly. Very good value for the product. Would purchase again. Shipping was on time as projected. I�m a very satisfied BikesDirect customer.

It's an Ultegra Rear Derailleur

Well it's an Ultegra Rear Derailleur, it's backwards compatible with the R6800 shifters but there's nothing to say, it work great, the only down side is the cable housing included in the box is a break cable housing so don't use that.

Great Upgrade for my brother's Giant TCR Advanced Pro 1

Got the GS Mid Cage version for my brother's Giant TCR Advanced Pro 1. A great upgrade from the RD-6800-SS short cage, was limited to 28T. Now, with the extra gears, I can climb hills with ease.

Well designed

I currently set this up w a 5339 11-30 cassette. I initially used a wheel with a 11-32 and it worked perfectly but downgraded since I mostly race crits. You'd definitely need a medium cage for 11-34.

Replaced my Ultegra 6800 derailleur with the new one and right away noticed an improved smoother shifting and quieter than the old model also its designed to be more hidden to prevent damage. Sleeker design and color probably one of the best upgrades for your bike.

Typical Shimano Ultegra quality at great price

In the process of switching several of my bikes over to 11-34 cassette compatible which requires the RD-R8000 mid-cage derailleur. Have ridden Shimano Dura-Ace and Ultegra lines for years. Ultegra delivers excellent quality and performance at a more affordable price. Definitely recommend this derailleur if you want to be able to accommodate up to 34 tooth cassette.

Nice Upgrade!

Upgraded from a three-year-old 105 derailleur. The new ultegra provides a noticeably crisper, more defined shift from a worn out 105 - longish cage accommodates 32t with ease. Why use anything else . . .

Excellent for running an 11-34 cassette. 20% grades only hurt badly now and aren't killers.

This derailleur allowed me to upgrade my cassette to an 11-30 cassette and its just been great. The shifting is quick and smooth and it just looks great too. The trickle down technology from the Dura Ace, makes this decision a no brainer.

You need this for cassettes over 28 teeth, i.e. 32, 34 etc.. Because of the dog-bone link extension, it works more like a short-cage design. I don't notice any difference in shifting.
