Dura-ace shifters w/Ultegra rear der.(5 posts)

Dura-ace shifters w/Ultegra rear der.rmlee

I just purchased some new Dura-Ace STI levers to replace my worn out Ultegra levers and I'm having a little trouble getting the shifting of the rear der. to dial in. It seems to shift fine between the smaller cogs and between the larger cogs, but it's not as smooth between the middle cogs. I've played with the cable tension a bunch and I can't seem to get it any better. I've spent some time looking at the cable routing and I think it's fine, and I don't think there are any burrs in the cable housing (I was pretty careful cutting it). Could this be a problem of matching Dura-Ace shifters to an Ultegra rear der. (this seems unlikely...my touring bike has Tiagra levers matched to an XT rear der. and it's fine)? Maybe the Ultegra rear der. is worn out (but it seemed to be OK with the old shifters)? Or is there something I'm missing?

Thanks in advance for your input.

If the stuff is all 9 speed there is no compatibility issue.Check the cable mount at the RD.

Also check that chain is not old and worn, or cassette is old and worn. That'll cause odd shifting problems.

I found myself installing shifters and just hooking stuff up in any old order. I had a lot of trouble getting it to work well. It went much smoother when I unhooked everything, bothered to read the instructions and connect cables at the proper time.

Also, I found my recent 105 double much easier to set up than any triple.

They should be completely compatible. It's probably something else. Lube the cables? Clean the guide under the frame? As posted already, worn out chain or cassette? Perhaps reset your limit screws?

Also the cable cinch on the rear derailler being right along the alignment groove. I had this off once and it caused similar symptoms.
