    Dura Ace 7 Spped Downtube Shifters?

    I bought from Ebay what was advertised as 7 speed Dura Ace downtube shifters. When I installed them, they only click five times from one end to the other. Could these be 6 speed or could I have installed them wrong?

    if they only click five times then they are 5 speeds not six or seven. one thing to try is disconnect the cable from the rear dérailleur and move the shifter and see how many clicks are there. you may have the tension to tight , if it is to tight and you will not get the right number of clicks.

    Yes. Unless you have something keeping it from shifting all the way like a tight cable, you have a 6 speed.
    You're just trying to start an argument to show how smart you are.

    what is stamped into the shifters, assuming you can find them?
    Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

    Nothing stamped on the shifters. Don't you just love Ebay. Guess I'll keep looking. Thanks for your replys.

    6-speed - 7400 silver
    7-speed - 7401 greyish (darker than 7400)

    My six speeders really only "click" 4 times nowadays because they are so worn. It's more like frindex shifting

    Check the clicking one more time w/o cable installed just to make sure (unless that's how you already tested them). Also check the bezel housing to make sure it's pointing to "Index". Something in between may not work correctly.

    Could also be the washer is rotated 90 degrees on the boss and it's running into the downtube at one end or the other. Worth a check.

    I've installed that shifter every way I can and it still clicks just like my 105 6 speed. Am currently searching Ebay for some 7 speed shifters. Thanks for your help.

    Use 8 speed Shimano shifters for non-Dura Ace 7 speed indexing. You could still buy them new the last time I looked for them.

    IIRC, 7-speed "guts" from Shimano 600 shifters will work in the Dura Ace levers.

    That would mean both the high and low gear positions are defined only by the limit screws.

    I think that is correct, I had never noticed it before...
