Half link?

    I'm having a hard time wrapping my mind around the purpose of a half link. I know what it looks like, but I just don't understand what it's for? When I alter my chain, I ditch the master, knock the pins out, shoten, flare pins and I'm good. Once I had to take a roller out, but I can't remember why. I believe the ends wouldn't jive. Is that where a half link comes into play?

    Yep, you answered your own question. As simple as that.
    Keep looking up! Ken.

    one full link consists of 2 inner plates and 2 outer plates - breaking a chain usually removes 2 outer plates (1/2 a full link) and a master link will connect the sets of inners together at this point the chain can be made another 1/2 of a full link longer by adding the 1/2 link which has bent plates that form an inner on one end & an outer on the other

    NOTE: 1/2 links for 415 chain are usually too fat or too thin at one end to fit both 415 and the popular 415H, so require some filing or grinding

    Yeah, those full halflink chains are handy for getting chain tension perfect. I've run KMC HL710L on my bike's jackshaft for several years.


    Yeah, there's just no room for sprocket wobble (tough to achieve with ragjoints) and the chainline has to be about perfect when using 410-type with the 2-stroke kits.
