Issues with Jagwire inline cable adjusters

When I built our Calfee Tetra I installed Jagwire J2 inline cable adjusters in the derailleur cables. They have performed flawlessly for over a year. However when I was checking the bike out for out trip to Indana for the ITR I found that shifting from the middle ring to the big ring was not smooth. I attempted to adjust the cable and found that it was frozen, probably from sweat. I took it off and with the use of pliers and WD-40 I was able to get it functioning again. I reinstalled it and adjusted the cable for proper shifting. We rode the first evening and after shifting from the big ring to the middle ring it would not shift back to the big ring. I could tell by the position of the ferrul that the adjuster had slipped. I stopped and readjusted the cable and everything shifted fine. Over the course of the three days this happened everyday.

Upon arriving home I installed a new Jagwire original cable adjuster with the same results. I then bought a new set of the original Jagwire cable adjusters and installed a new one, same results. I have now taken the adjuster apart, applied Loctite to the threads and it is now functioning as it should, i had to use pliers to make a minor adjustment.

I just ordered a set of Shimano inline adjusters.

Has anyone else had this kind of issue with the Jagwire adjusters and if so how did you resolve the issue?

It sounds like the same problem we had and still have. http://www.bikeforums.net/showthread...ion?highlight=

We temporarily solved the problem going to Jagwire Rocket indexed adjusters. http://jagwireusa.com/index.php/prod...cket_Adjusters
I've heard others report durability problems with the Rockets with high cable tension, but we had two or three seasons of reliable use.

Unfortunately I've since had to install Jagwire inline adjusters to allow for a handlebar bag for touring. During a ten day tour I had to make half turn adjustments about every second or third day. I previously thought it was due to tensioning and untensioning the cables during transport ( we have a coupled bike ). But the cable tension continues to change when the bike is left coupled, and we just ride. I'm at a loss to explain why we have problems and others don't seem to.

Loctite solved the problem, on our ride this morning the adjuster did not move.

I chased the same problem on my cross bike with those for a very long time and finally just gave up on them completely. I never tried the loctite solution.

I've kindof learned to live with it. All the sets I've had do move. Thought of trying loctite but figured I wouldn't be able to adjust afterwards (has anyone tried carbon assembly paste???). For the right shifter I always back it all the way off and make my main adjustments with the derailleur barrel adjuster (one reason I stuck with an m952 RD over a shadow RD). On the fly it rarely needs touching and always tighter if necessary. For the left shifter I have to use it and listen for when the FD is having trouble before I adjust. I find rough roads and long journeys with the tandem on top of the car are most likely to cause "auto adjustments" to occur. Sure wish there was a better adjuster readily available. Or Shimano would use barrel adjusters again.

I also had problems with in line adjusters. Luckily my current tandems have adjusters on the cable stops. This is a great design used by some frame makers for decades.

I have a set of these on order, http://www.amazon.com/Shimano-SM-CA7...cable+adjuster

With the Loctite applied I can still make adjustments, it does however require the use of pliers.

If the Shimano ones do not work I am going to try these, http://www.amazon.com/CABLE-ADJUSTER...cable+adjuster

Our Co-Motion doesn't have cable stop adjusters and neither does our XTR rear der.
I purchased one of these to put on the XTR the next time I'm changing cables, and I'll ditch the in-line adjuster. Hopefully it holds cable tension better. Not sexy, but at this point I don't care. http://www.rivbike.com/product-p/ca52.htm

Our Speedster did not have them and that is where I learned about in line adjusters' problems. Such is progress. As mentioned above some improved rear derailleurs also no longer need them.

Here is the latest installation in this saga. The Loctite on the Jagwire adjuster also failed! The adjuster rotated and lost tension on the cable. It happened during a ride and I needed to up shift from the middle ring to the big ring so I just reached down and pulled on the wire to move the front derailleur.

I have now installed a Shimano SM-CA70 Cable adjuster, which I ordered from Amazon.com and it is so far performing flawlessly. I also installed Nokon shifter cables/housing and the front and rear shifting is even better than before. I also removed the inline cable adjuster from the rear dérailleur cable.

I have used those in the past and they worked well for a lot of miles then developed some small slippage and the outside became worn and they now look really bad. I have saved them and if I need inline adjusters again i will give them a try.

I also have had trouble with the screw moving, but only on the front der cable, not the rear for some reason.

I put a small dot of paint on the base and on the moving part, so I can immediately see if it moves.

I had the cables loosened yesterday for another issue, and while they were loose, I filed the "valleys" of the detents deeper on the base. Hoping that'll work, I'll report after a couple rides.

Edit: filing the detent's deeper absolutely stopped the "drift" in the adjusting barrel. Rock solid.
