Clutched derailleur or not?
What has been the general consensus so far for a clutched rear derailleur?
Ive only had on on a Cutthroat, and thought it worked great in that setting. My road bikes never had up to this point.
I am building up a DI2 all road bike and am looking for input on the RD. I’ll likely go for the 11-32 cassette. I’ll be on pavement 85% of the time, and the rest on smooth gravel, nothing too gnarly.
thanks for the input

I've got the Ultegra RX (R8000) on my gravel/all-road/rando bike and think it's great. That said, I don't have a clutch rear mech on my older hard tail mountain bike and it hasn't ruined my life. Though I do notice considerable chain slap whereas my gravel bike has absolutely none. If you'll be on pretty smooth surfaces most of the time I'd think you'd probably be fine without the clutch. But there's also no point in handcuffing yourself if you decide you want to take on a little rougher terrain in the future so a clutch mech might be an investment in future-proofing.

Good to know. I’m about to embark on my first DI2 setup and want to think everything through the first time.
Maybe I’m not looking correct, but I don’t see the RX800 DI2 on the Shimano website. Is the GRX DI2 the current replacement for this? If that is the current replacement it looks like that should work good with the current Ultegra and DA DI2 correct?

Last year I bought a Jamis Renegade with a lot of firsts for me: 1st 1x drive chain, first use of SRAM components, first clutched rear derailleur (Force 1).
I use it for unpaved rail trails/towpath, gravel roads and bikepacking road riding and so far I'm very impressed with the shifting and the lack of chain slap - but with all those new things to me, hard to say how much is due to the clutch.
The clutch definitely makes getting the rear wheel off easier, or at least easier to keep my hands clean while doing so!

If you are going DI2 anyway why wouldn't you get the clutch? I mean the only real downside I can think of is it takes a bit more finger effort to change gears but Di2 eliminates that issue. And I guess a hair more weight but meh.

the smaller your small chainring
the closer your chain will be to the chainstay and the more likely it will get slapped by the chain. clutch could be helpful. also if you run a big cassette your chain will have more slack in small-small combinations. i run 48/32 up front and 11-36 in the rear with the non-clutch rear derailleur and i don't get much if any slap. but given another opportunity i would definitely opt for clutch for insurance.

Can't imagine wanting one for a road bike. The ultegra clutched rd on my gravel bike is often not engaged, so omit would go to even less use on a full pavement bike.
