Barrel adjuster XT rear mech
Barrel adjuster XT rear mech
I've bought a second-hand bike and the rear mech barrel cable adjuster is missing. The mech is a Deore XT RDM771. I've tried the adjuster from a 9 speed Deore mech but the thread is different.
Does anyone know where I can get an adjuster that might fit? I've seen one for a XT RD M760 at SJS Cycles but am unsure if it will fit.

Re: Barrel adjuster XT rear mech
Are you sure that the threads are different and that the missing mech's thread isn't just worn or stripped? I had to re-tap the thread on a Deore mech the other day.
To source - go to the LBS as they'll doubtless have all sorts of old worn out mechs that might be robbed.

Re: Barrel adjuster XT rear mech
the reason the barrel adjuster is 'missing' is because there isn't one fitted to this model.

Nor is the mech tapped to accept one. I suggest that you fit one inline somewhere, or use a barrel adjuster with a rubber wedge on it that is designed to fit into a cable stop; Bontrager make such things.
cheers

Thanks Brucey that would explain it! I'd already bought a couple of different inline adjusters in case I couldn't a replacement for the (nonexistent) rear mech one.
Re: Barrel adjuster XT rear mech
I imagine they stopped having adjusters on the rear mechs because they were a bit vulnerable to damage, but it is a pain for those of us who never broke them. I managed to fit an inline adjuster (possibly modified, I can't remember) into the recess on the mech, and got it to work. It sticks out a bit but I've not had any issues with it.

MTB type derailleurs are designed to be used with flat bar gear levers which usually incorporate a cable adjuster. No point in having one at both ends is probably the thinking.

Yes. I suppose my problem is that I put components with other components Shimano didn't expect me to. I also have the down tube adjusters, but I prefer to have two adjusters in there. I bet I could make do with one if I spent more time getting the tension perfect on initial installation.

I use Jagwire minis. They work okay.
There is your way. There is my way. But there is no "the way".
Re: Barrel adjuster XT rear mech
If it aint broke, fix it til it is.
Re: Barrel adjuster XT rear mech
One good thig to do, is to lubricate the threads while fitting those adjusters. After a while they seize up, thus becoming a "cable stops" rathen than "adjusters"
It is by riding a bicycle that you learn the contours of a country best,
since you have to sweat up the hills and coast down them.
Thus you remember them as they actually are...

I bought a pair in Red, but only needed one so I have a spare.
This is mine on the Moulton with an XT rear mech. Yes, that's correct.
