Ultegra adjustment issues(15 posts)

Okay, I checked out the links to derailer adjustment and tuning yesterday and made some progress on mine. I now have the derailer working perfectly from the smallest cog through the 6th, but 7 and 8 are a mess. If I make barrel nut(?) adjustments to get 7 and 8 working well, the lower gears get out of wack. How do I get them all working correctly?

Sounds like your derailer hanger is bent. Shops should have a tool to test and adjust the hanger if necessary.
pretty sure it's not bentt0adman

I had an LBS guy I met at the Seward Park criteriums take a look at it and he didn't think it was a bent hanger. The bike only has about 250 miles on it and was never crashed. There's something fishy going on here.

If the derailleur isn't out of alignment, and the chain shifts perfectly to the third cog out, but won't go to the last two inner cogs, could this be because when you try it, the chain is always on the outer chainwheel?

Despite what many say, no chain will easily shift from the outer chainwheel to the last 1 or 2 inner rear wheel cogs. The chainline is too skewed.

By the time the chain is on one of the bigger freehub cogs, it should have been shifted into the the smaller chainwheel. If the chain shifts perfectly on the outer cogs, front-to-back, it should also shift on the inner cogs, unless the chainline is way out of parallel with the cogs.

and can shift smoothly up and down all nine cogs while on any chainring.

Try starting over. Loosen the cable.

Set the outer limit screw. Set the inner limit screw.

Pull on the cable and "upshift" until you have maximum cable extension. Pull the cable tight and fasten on the correct side of the mounting bolt.

Try shifting with the chain on the center (3x) or inner (2x) chainring. One click should go to the second cog. If not, tighten with the barrel adjuster.

When it does, leave it on the second cog and tighten the barrel adjuster until the chain gets noisy as it tries to shift. Back off the barrel adjuster until the noise quits. Shifting should now be perfect through all the cogs.

If still a problem:
Check that the cable end on the lever end is set into its indent properly.
Check, again, that the cable on the derailleur is mounted properly.
New derailler?Dropped

I had a similar problem with an old derailler that was so worn out that the bushings had oodles of play. Just couldn't get it adjusted to work with all the cogs no matter what. Switched to a new derailler and it worked perfectly.

If you derailler is new, I can't help ya! ;)

I have had the same issue when I set up my new FS with an XT derailleur. I bought the frame from LBS and switched over most parts. Once I got it assembled, I was in the same conundrum. Took it to LBS and they swore my rd cage was bent. I disagreed and told them I would work on it some more. I finally figured out it was pertaining to the tension from the cable.

You may not have enough tension from the cable and this may be preventing you from shifting to the largest cogs. I would shift down to the 11/12 T. Bottom out the barrel adjuster by turning it clockwise, towards you till it stops and loosen the nut on the cable stop and then tighten it again using a pair needle nosed pliers holding the cable with some tension on it. Then tighten it, you shouldn't have to adjust your h and l screws, just your barrel adjuster.

This worked for me.. but I may be wrong.

Same thing for myself. On my old mtb my Sram derailluer would not shift well between the three largest cogs. I just built up a new bike using the same parts, ran into the same trouble, but was able to fix it, turns out it was due to lack of enough cable tension.

Take Theweasonator's advice.

How old is the cable and cable housing. If you have too much friction on the cable that could explain the problem. If they are old, try new cables and housings and also check cable routing.

Okay, it's a 2002 Lemond Zurich with less than 250 miles on it. The cables might be lengthening and I've tried adjusting the barrel nut with some success. The bike is in great shape (almost new) and has no damage. I'm trying to shift from the inner ring of a triple but I have the same problem on 7 and 8 in the smallest front ring. I never try to get that high on the largest chain ring, and vice versa from the small one.

Have you tried disconnecting the cable and working the small lever nine times to make sure it's at it's lower limit? Load the chain on the smallest cog, snug up the cable and try again.

And with the loose end, pull all of the slack out of the cable while you work the small lever.
This being said..........have you consideredcoonass

that the shifter may need a little TLC?? Wouldn't take much time to give it a shot:
(maybe it's not the tail, but the dog that needs attention) Tooooo much time on my hands :)
Double check that you have the cable attached properlyKerry

Sometimes people anchor the cable on the wrong side of the anchor bolt, and then things simply never get right. If you didn't change the cable, then this obviously is not your problem.
Thanks to all...t0adman

I spent some time messing with the barrel nut on the RD and finally got it working correctly. Minor issue that I managed to make major. Thanks for your help everyone.
