    “Quality chain tool”

    The Good: Solid feel, fits nearly all chains

    The Bad: Probably too big/overkill to take in your pack

    Overall Review:

    You might be tempted to try and save a few bucks and use the little chain tool on your fancy multi-tool for home bike repairs, but this tool is much better. I am of the philosophy that the fewest times you have to replace pins and "brake" your chain, the less likely you are to have problems on the trail with it. Park's tool here gives you the best chance at keeping your chain in proper order and offers a big enough handle to transfer the nuances of pin pushing to your fingers. My favorite feature is that you can easily tweak any stiff links without resorting to the bend-the-chain technique.

    “Shop quality chain tool, own it for life”

    The Good: Strong, durable, replaceable pins

    The Bad: CT-3 may not work on 11 speed chains. The newer CT-3.2 works on 5-11 speed chains.

    Overall Review:

    I've used this chain tool for over 15 years without fail. So far, I have replaced one pin.  The steel construction and fine machining is both durable and smooth.   The rubber coated handles are also a plus.   This tool also works loose kinks in the chain.  Not much more to say than buy this tool and you will own it for life.

    “works how it should”

    The Good: Works exactly as advertised. I have replaced multiple chains and it has been perfect. Even the dreaded shimano link pops in very simply. I thought it was worth the price.

    The Bad: I have no bad issues with this. As of now no problems whatsoever.

    Overall Review:

    I would recommend purchasing this item. I always think it is worth it to have quality tools in your arsenal.
