If you know the size (thread pitch and length) McMaster-Carr sells pretty much any screw you might want (you won't be able to get onesies, though - with itty bitty screws, you are looking at a min of ~100 or so
have bought small metric screws at home depot ((nm)Paul

How do you like your UltegraDWridesGT

I am getting a pair of Ultegra STI shifters this week. I have heard horror stories about them rattling, weak shifting, poor craftsmanship, etc.... But, I have also heard (from different people)they work flawlessly and shift smoothly. I know every story has two sides, but what do you think about the Ultegra STI shifters.

The 6510 model with the screw holding the front cap on is much improved. It also has a small rubber bumper to keep the small shift lever from rattling against the big one.

Still, my 98' STI Ultegra shifters are still working too, and once I fixed the cap with some silicon glue, it has been pretty quiet. In some ways I like it better than the newer model, since it is not as sensitive to pressing the wrong lever. If the big lever is even the slightest bit moved while the small lever is pushed, then you can't shift those 6510's. The old ones are not nearly as sensitive to this, but maybe because they more worn?

Always looking for excuses to mess with the bike I pulled one (yeah I almost dropped it) from my
Ultegra and measured: 2mm (dia.) X .5mm (pitch) X 4.5mm length, roundhead
This is fairly close to UNF 2-56 or that oddball #3 size, either of which may work in a pinch since you're only going into plastic.

My shifters are actually labelled Ultegra 600, which I guess are the cross over model. They were
brand new Feb 96 and are still going strong, they do rattle a bit now, and the small (inner) levers needs
to be pushed about 2cm/.85 inch before they engage. I know the new ones are responsive as
soon as you start to push them.

I have never had to adjust or replace anything other than chains.

They work fine but for....bear

hey LC the shifters are great but for the problem of the little screws caming off and days later you realize what happen,,the LBS can help or wont. I cant believe they dont know about the problem,,once I get the new screws I am using a drop of locktight on it it should be fine. I am building a new bike with all ultegra,,best punch for the money.

Yank one of your shifters and go into the metric stainless steel section of any Ace hardware store. There will be only one size & pitch that will fit easily, but they'll all be too long and the head will be different. Go for the pan head style and shorten the screw. Here's how to shorten it - place the head of the screw between to small blocks of wood so that it won't get damaged and place the whole works in a bench vise. Now use a hack saw to trim to length. Now get a good file and trim the burr and lightly put a bevel around the end. This will allow the screw to easily thread into the hole. Next apply a little dab of BLUE Loctite and secure the screw and it won't come out. You *really* want to do this soon b/c if you don't the shifter will start coming apart internally and it is a real bear to rebuild them.

don't forget to clean the hole and the new screw with some solvent, the longer the better, and add loctite in there and onto the screw. Worked well for me and doesn't loosen up!


Woof, the dog with a couple of screws loose.
Did you check Third Hand Loose Screws?mja

I had that same screw back out and leave my 105 levers. I could not easily find a replacement so I took it to the LBS where I bought the bike. They had to order it from Shimano, but about a week later it came in and no more blasted rattle.
