I’m working on a bike for someone and it’s got this problem that I just can’t seem to figure out.
It’s got DA 9sp. bar ends, and they seem to just glide over certain clicks. It goes from the 2nd cog to the 4th cog without a solid click for the 3rd. If you shift realllllly slow you can feel the groove, but it just doesn’t lock in. It would be impossible to make that shift while actually riding.
Yes the shifters are set to SIS and not friction, any ideas?
Thanks.
Yes. Forgive me for my descriptions because it has been awhile since I had the same problem. When you assembled the shifter there is an insert/washer/disk “thingy” that goes between the actual lever and and bar-end fitting that goes into the bar. Likely problem is that “thingy” is not oriented correctly with respect to the shifter when you put it together. Take a look at the instructions carefully and make sure you have the orientation correct or else you won’t get 9-speeds.
Sorry, but my take is that it is wore out. I had the same prob a few years ago with a click that disappeared. I tried everything possible to reinstate that missing click - no joy. The sucka was just worn out. Bought new barends and - voila! - sharp, crisp shifting of all the gears was back in town!
I believe that the square notch has to be pointed down when the shifters are mounted in the traditional orientation on the bars…
I was retro-fitting an old road bike from STI to bar-ends, Ultegra 8-speed, for my current tri set-up (softride, to easy to get steeper). New Shimano 8-speed bar-end shifters from Harris Cyclery (new-old stock). Could NOT get the shifting dialed in no matter what I tried. And this is with new cables and housing, all lubed up nice. Solution? Go to friction. Not a big deal for me.
So I guess my short answer is that I have no answer…
yeah, you have the shifter put together wrong. The indexing probably wasn’t set all the way to one extreme when you reassembled them. How to fix it, I’ve done it a few times but usually my old shop guy did it, so I’m of no real help. I swore there were detents worn out as well but it usually just needs some adjustment. good luck
I posted the following response to another person describing a similar problem. It should fix it.

I believe I know the problem you are having (same thing happened to me). The shifters have both 8 and 9-speed indexing at opposite ends of the range. Basically something like 9-9-9-9-9-9-9-9-9/8-8-8-8-8-8-8-8. You’re in the middle of the range so you’re getting very bad shifting at one point (sound like 3-5) and iffy shifting above or below this point.
You need to “reset” the SIS shifting. If it’s a 9-speed system, shift the level as far forward as possible (forward being the direction of the kink in the shifter). Remove and re-set the shifter in the housing if necessary to make sure you shifted to the limit (this is key!). This will put the shifter in the proper indexing for 9-speed starting with the smallest cog on the cassette. For 8-speed, you will want to shift the lever back and you’ll be in the largest cog on the cassette.
Hope this makes sense. PM me if you have any questions or problems.
Joe
That makes sense, I’ll give it a shot.
The problem as you describe it is exactly as it’s occuring.
I’ll give it a shot and let you know.
Thanks.
Joe,
Thanks that did the trick!
Great, but don’t thank me, thank Jack of Jack and Adam’s. He’s the one that helped me.

I believe the 9 sp DA bar end shifters only work properly with the DA rear der. Apparently they don’t work properly with Ultegra or 105.
Perhaps a bike mechanic can verify this?
In 8 spd mode, yes, DA is only compatible w/DA. In 9 spd mode, DA is compatible w/all S/O 9 spd.

I have dura 9 bar-end mated with 105 rear…works great.
I have a crappy old steel bike with new D/A bar end 9spd they are working great with an older Ultegra triple rear and a 53/39 front.
