## Description

desertcart.com : SHIMANO Ultegra RD-R8000 Rear Derailleur Gray, Medium Cage : Sports & Outdoors

Review: Excellent derailleur - perhaps the most worthwhile upgrade from 6800 - TL;DR: Excellent product, a real improvement over the previous version. I bought this to replace a 6800 RD that I snapped off of my bike. I used to have a road link to allow for bigger cassettes without any problems. This version has a "road link" included in it. Installation is a bit different than the previous versions: First, the shift cable fastener thingy feels much more sturdy and routes the excess shift cabling neatly behind the derailleur, so it doesn't stick out anymore. It has much less chance of catching something and fraying. Another change is the indexing knob - it has this tiny lock that you need to actuate in order to turn around. Indexing was a breeze - took literally five minutes and now shifting is flawless on an 11-32 cassette. I need to try it with my 11-40 but watching some youtube videos it can tackle it no problem. This is maybe the most worthwhile upgrade from 6800, is completely backwards compatible. This is the first time a Shimano road derailleur works flawlessly with up to 11-40.
Review: Great Product Highest Quality - You can not beat the quality in design and engineering with SHIMANO. Even their lower cost items are of exceptional quality. I upgraded from the SHIMANO Ultegra Short-Cage Rear Derailleur to the Mid-Cage. This allowed me to increase the size of my rear cassette from 11-28 to 11-34. I have even gone to a Shram 11-36 and love the performance.

### ⭐⭐⭐⭐⭐ Works great!
*by N***S on February 12, 2018*

Very easy bolt-on, slightly finicky initial alignment setup....but it worked GREAT with my 6800 shifters on a 42 mile hilly, windy ride, so there was LOTS of shifting. Didn't miss even one, and it passed the ultimate test, it crosschained without complaint on the 34, and was even quieter than my 32 tooth setup while doing it!! And of course, the bailout gear was welcome climbing into a stiff wind. Two thumbs up on this one! Hot tip: Have an extra shifer cable on hand BEFORE you install, just in case you bugger up the end of your original cable, or it should end up an inch too short. Don't ask how I know this.
