barrel adjuster recommendation

Anyone have a suggestion for a good in-line barrel adjuster?

I have adjusters next to the brifters. Very handy since we have a travel bike and use cable splitters. However, the adjusters I have on the bike (lbs installed) appear to slowly turn during a ride, as much as 1/2 revolution. I had been blaming the poor shifting on the wide range cassette, but when I have it dialed in it's not great, but acceptable. It's a very small sweet spot, so small adjustments make a difference. I had attributed it to frequently uncoupling the S&S connectors and splitting the cables and traveling with the bike. It became a standard procedure to make small cable adjustments before each ride. But we have recently done a lot of rides from home with no fussing with the cables. Often during a longer ride shifting would get worse. I finally realized what was happening and used a sharpie to put bench marks on the adjuster and noticed that it slowly turns. As a stop gap I put some tape over the adjuster to keep it in place.

Our XTR der. doesn't have an adjustment so that isn't an alternative to in-line.

Has anyone run into this before, or is this a freak occurence?

As for the problems your adjusters are exhibiting, the only time I've seen things like that "loosen" is when a cable is allowed to go slack when the threaded interface isn't all that snug.

As for in-line adjusters, I like the Jag Wire Mini In-Line derailleur adjuster... the one with the black rubberized coating. Nice tacticle feel that makes for very small, precise adjustments on the fly. It's the lower one in the attached photo; the upper is the OEM Avid in-line brake cable adjuster.



BTW, and I forget who was interested in them.... my DuraAce in line gear position indicator came apart after about 3k miles of being bent at an awkward angle due to the short cable run between the underside of the bars (remembering that Campy routes the shifter cables under bar tape) and integrated head tube cable stop. So, I'm back to looking between my legs or, as if often the case, hearing a reminder from my beloved stoker, "You're already in the middle ring" or "You know that you're in the big ring?".

I have adjusters a bike that never move. I believe just a Shimano part.

I had a Jag Wire in line adjuster that kept changing on my cross bike...drove me nuts. Finally replaced it with another (the same silver plastic jagwire not the cool rubber coated one in TG's photo)and it no longer is an issue. Have no clue why it did it or why it stoped as both adjusters were new.

Regarding the Dura ace inline gear position indicator...that is the greatest single upgrade piece in the history of Tandems ever!! Have them for BOTH deraileurs and would be lost without them when the roads turn hilly!

Follow up to my original post. I installed a Jagwire Rocket barrel adjusters in place of the inlines. They are indexed so should solve the unwanted rotation issue. At least with the bike on the rack it is shifting quite nicely. Won't find out for sure for at least another month if the weather doesn't break.

Unfortunately after installing the adjuster I found that it greatly increased the interference with our Ortleib handlebar bag that we use when touring. Forces the cable housing in a very tight bend. I'll see how it goes this summer. If its a problem I may try an inline adjuster again. Maybe a Jagwire like TG used. The Jagwire stuff appears well made.
