    resizing a chorus ultra narrow chain

    I just got a new chain because my record ultra narrow chain got bent and I ruined it trying to break it and add some of the extra links I removed when I sized it for my bike. The guy at my local BS told me that you can't do that with the ultra narrow chains. He says that you size it, install it and ride it till it wears out or is damaged in which case it needs to be replaced. My problem is that I just got a new frame and I'm pretty sure that the distance between the crank and rear wheels is shorter. So, can the chain be shortened or do I need to buy another new chain to use on the new bike?

    thanks!

    Do you own a chain tool?

    You need to buy a CN-RE400 chain link from your Campagnolo dealer.

    Break your chain using a 10spd compatible tool, remove the amount of links you want and then use the CN-RE400 to re-assemble the chain.

    READ THE INSTUCTIONS FIRST.

    Always remember that you want to push a pin into a hole in the OUTER PLATE that has never been used before so, when you are removing links, remove them in such a way that both ends of the chain are inner plates.

    You either need one of the compatible master links, like the one Bob lists, or Wipperman, or use the Campy kit which is a set of links that end in outer plates at either end and come with the pins. I would go with the master link, it is about half the price of the Campy kit.

    The Campy ultra narrow chain is 5.9 mm in width, is the Shimano the same width? I've been unable to find that width at the Shimano sites.

    I would need to double check to be sure, but I recall that the Shimano is a tad wider.

    Wipperman connex link, 6.1 mm works. Just use a regular chain tool to push out a pin to shorten the chain.

    This will work but you will hear it when you ride.

    I had one fail on a Record chain after 10,000km or so.

    It is a lot cheaper and convenient, though.

    The only data I have is that Wipperman's 10X1 Campy-compatible 10-speed chain is 6.2 mm wide and Wipperman's 10S0 Shimano compatible 10-speed chain is 6.0 mm wide. Campy's new ultra narrow 10-speed chain is 5.9 mm.
