Mentioned this RD in another thread.....thought maybe it deserved a thread of it's own.

I am interested if anyone has ridden ideally as part of a 2x drivetrain, but will gladly read 1x feedback too (smile).

It's a new'ish clutched mechanical Ultegra rear derailleur with an on-off feature, which can be used 1x or  2x - 16 tooth systems, paired with 11 speed cassettes up to 11-34 (and we are guessing a touch more).

Again, would love to hear from those who have ridden this model.

searched for reviews from riders on this site but didn't find, apologize in advance if it was a lazy search.

When they become available to purchase I plan to buy one. Until then you can watch the BikeRadar comparison between the clutched and non clutched Ultegra RD.

Was going to do this for my "ghetto" 1x Shimano setup but decided the heck with it, I'm going Sram Force 1 to get a proper dedicated 1x system.  One day Shimano will catch up and offer 1x road stuff....

GHC,

I apologize if you are already aware of this, but there's two 'tension' settings on Shimano road rear derailleurs. They come stock in the low setting and only take a couple minutes to move to the high setting. I'm at one chain drop in 3 years of CX racing and gravel rides since using the high setting on my 105 and Ultegra RDs. I'm happy that Shimano is offering a clutched system too, but I can't say I will be buying one.

^^^Yes, I did this and it helped some for sure.  Look, my bike has decent chain retention with the Shimano road 1x setup but I have run a n/w ring and a chain guide.  If I am hauling @ss over rough rooty sections (so in a small cog w/ slack chain) it will still jump around.
