    Are 9s and 10s shimano replacment pins the same?

    Does anyone have a 9speed versus 10 speed shimano chain pin picture? I need to shorten the chain on my 9 speed mountain bike for a long ride tomorrow and have a replacement pin but don't know if its 9s or 10s. The discarded portion has three evenly spaced ridges but I can't find a image on the net that looks exactly like it.

    Any help would be appreciated, I'd hate to make an unnecessary LBS trip.

    I've been told "no" they are not the same. I have a little container marked "9 speed" and another marked "10 speed". Chain pins in each per my LBS.

    I learned on one trip that there are two different replacement pins for 9-speed...one as you describe, with the 3 ridges, the other without the ridges. All I can remember is that the one without the ridges is the one I use for my Ultegra 9-speed.

    Sorry if this just confuses things.

    I'm usually heavily pro-Shimano, but KMC makes excellent "quick-links" for 8, 9, and 10 speeds. They are completely compatible with Shimano chains, re-usable, and very easy to use. You shouldn't have to pay more than about $5 or $6 for one.

    Nevermind, I found it... wrong pin:



    A= 7 or 8 speed connecting rivet
    B= 9 speed connecting rivet
    C= 10 speed connecting rivet for model CN-7800
    D= 10 speed connecting rivet for model CN-7801

    The cylinder below the deep groove is the bit that stays in the chain. Note how each is progressively shorter as the "speed" increases.

    Go yo your LBS and get a Sram 8 speed quick link. They are reusable.

    An 8-speed link for a 9-speed chain? Don't think so.


    And I'd take KMC, Wipperman, or SuperLink over SRAM.
