|Dura-Ace STI left shifter... 2 clicks?||flate|
Jun 17, 2003 7:05 AM
|Just got my new Dura-Ace STI shifters installed, and although it is a ST-7700-C (Double), when i go to downshift (Large to small chainring), i have to go through 2 clicks, is this normal, or a defect with my left shifter? I am running a double set-up.

|The middle position is that you can trim the front changer, when you are in a big-big gear.|

|My '98 D-A shifters do not have any intermediate clicks (detents) like the Ultegras and others. I can trim (but never need to) by sliding the derailleur from either side up to 5mm, but this is like friction, not a click stop. I don't know if the later model D-A double shifters have been changed. The Shimano European web site has more technical information than the U.S. site, suggest you check there.

|1. small chain ring, largest cog. You should be about 1 mm away from inner der. plate. |
2. Large chain ring, smallest cog, same as above distance from outer der. plate..
You will probably see that you have much more distance when in number 2 position, why you have to trim/adjust.
sounds like you not sure, so don't mess with it. LBS know that they will need to adjust. I would start it from scratch, but it's too many instructions. Ask you LBS for the instructions that came with the shimano equip. that you purchased. Buy a book on bike mechanics about 15.00.

|RTFM as they say... it is indeed the trim click. It is very well indicated in the manual.... that the lbs didn't leave me... oh well.
thanks to everyone
