Clutched derailleurs

Postby lone rider » Wed Mar 14, 2018 11:21 am

Anyone else given up on them?

Ive tried my best to tolerate the slower, crappier shifting and then there always seems to be a gear in the middle of the cluster which just doesnt sound good when the clutch is on but after never breaking a chain in my life and having 2 seperate ones break on this bike only Ive given up. Went for a 2hr ride with it off and it was bliss. I found it never totally eliminated chain slap anyway so not sure why I bothered for so long.

If you're running 1x up front without a chain catcher of some sort then the clutch is essential. You will throw chains and eventually it will happen at a terrible moment and you'll wish you still had a clutch :D

If you're running a 2x the front derr does the job and there's really not much point in having a clutch except to reduce slap which is really a cosmetic/annoyance thing that really doesn't matter that much.

If you're breaking chains I'd be worried something else is going on - is your maintenance schedule on point? Is your suspension design giving the chain an extra workout and wearing them out quickly? Chains don't just break because of clutched derrs - clutched derrs are so widespread now and there isn't an epidemic of chain breakages .

Shift quality is definitely a step down, I know, I just replaced a 105 derr on my commuter which shifted
flawlessly and effortlessly, with an XT and a tanpan and now it's just that little bit heavier at the lever and a bit slower on the downshifts which is a shame, but at least it doesn't throw.

I switched mine on the other day for the first time in...2 years maybe, was into a 4 hour race and I was tired so lots of little/little cross chaining over bumpy stuff, chain was clanking away, figured a little bit of help would be good. Otherwise, Im not a fan of the craptastic shifting you get.

I'm not a MTB rider but have heard complaints about KMC X11.93 chain breakage on 1X systems with Narrow-Wide rings.
I run the above chains on 2X road bikes perfectly well but wonder what type of chains you are using?

Using Shimano HG chains and I've built bikes and always done my own maintence and never had issues on any other bike. Am running a 2x so unless there is a far bigger problem with the chain line like rear triangle or wheel out of whack I think I'll keep it off and see how it goes. I have my doubts regarding having a tensioned chain during shifting and the effect on components.

I think I left mine off for about a year and still didn't lose a chain.

Been running 11sp and 10sp clutched derailleurs for about 2 or 3 years now.

Have the family MTBs all with clutched RDs now; 3x, 2x & 1x. Mind you they are all now Shimano and no shifting problems.
Anyone want any SRAM cassettes or RDs? :twisted:

You know the cassettes are compatible with your Shimano drivetrains, right? :wink:

I've had the opposite experience - went from Shimano XT type 2 to whatever the SRAM clutched RD is called. Much prefer the SRAM system, no fiddling about adjusting tension or turning on/off.
ALL THE ABOVEIS TRUE

I've broken two KMC chains in races, but I was tired and my shifting was getting very sloppy and late.

I wouldn't go back to non-clutched. It's not any better.

If you've ever ridden MY2010 Shimano XT Rapid Rise (aka Low Normal) 3x9 with shifting integrated into the brake levers nothing will ever come close for ergonomics and smooth shifting. This was the second generation integrated shifting and it was a huge improvement ergonomically over the first generation. Simply brilliant. Unfortunately it was killed off when 10-speed and clutched RDs came out.

I've only ever dropped my front chain twice in 5 years of ownership. I credit the clutched RD for that.

SRAM cassettes (and chains) are made of cheese. Shimano componentry is like a fine wine. So I suppose they can go together. :wink:

I'm not drinking fine wine with Coon cheese. There is a huge difference between "compatible" and "plays well together".

I have an Anthem with a 2x has an XT clutched mech and at one stage I destroyed it an borrowed a non-clutch mech and over rough ground when you weren't pedalling (descents) it would throw the chain off all the time.
I suppose it would depend on the riding you are doing, if you aren't doing big rough descents it probably won't be much of an issue. I know I love my clutch derailleur.

Had my first ever ride on clutched yesterday.
To be honest I didn't notice any shifting issues comparing my two bikes, 10 speed XT no clutch, the new bike 11 speed SLX clutched. SLX bike was silent with no chain slap and shifted beautifully.
