    Connecting Pin for Shimano 10 speed MTB chain

    I just set up a new 10 speed drivetrain and used the CN-HG94 chain. I want to buy some spare connecting pins, but I haven't been able to find anything online for the HG94, just for Ultegra or Dura-Ace chains. Are the pins the same for the Shimano road and MTB chains?

    Thanks.

    The new MTB chains use a different pin than all previous 10 speed road chains.

    Are you sure? The Shimano technical instructions say to use the 10-speed 2 or 3 groove pin for the CN-HG94 chain. The 2 groove is the normal Dura-Ace pin as seen here...http://www.rei.com/product/764677.

    I know the MTB and road chains are different, but I wouldn't be surprised if they use the same connecting pin. I just haven't been able to confirm this. All the places I've found the pins online always mention the Ultegra or Dura-Ace part numbers, but never the HG94.

    Luckily I won't need to worry about having a spare pin until the snowpack melts here in CT - probably early July sometime.

    # For Shimano HyperGlide (HG/HG-X) and InterGlide (IG) chains

    # New generation 10-speed road (7901/7900/7801, 6701/6700/6600,5701/5600) and mountain (M980, HG94/74) chains use a permanent three-groove/guide connector pin

    # 1st generation 10-speed (7800) chains required a single-groove/guide connector pin but are no longer available and should be replaced with a complete, new-gen chain

    10 speed SRAM is Powerlock and is not a reusable item according to SRAM. KMC and Connex make a reusable link that works with Shimano chains.

    It's strange that the Shimano Technical Instructions for the HG94 and the instructions that come with the CN6600 for my road bike both point to either the 2 or 3 groove pin as correct. I've been using the 2 groove in the 6600 for several years.
