    D.I.D. Track Chain Master Link

    So my chain got a little rusty and I decided to buy a D.I.D. track chain. I opened it up and see that the master link connects with a small screw and bolt. This seems a little goofy to me, especially considering it's a very small square bolt. Are there special tools for breaking this chain or attaching the master link?

    apparently all NJS track chains must come with small bolt to attach the chain.
    small bolt makes a lot more sense safety-wise that having two interlocking plates with goofy oblong cutouts.
    track bikes don't have multiple gears so having a bit of a bulge for the screw head has 0 net effect on the bike. (whereas on a multi-geared bike it'd affect shifting)
    If steel is real then aluminium is supercallafragiliniun!

    I've used a DID for singlespeeding for about a year now. One hella strong chain. Just replaced the chainring--wore out and measured the chain with a checker. Still less than .75, probably around .30 in stretch. You can break the chain with a regular tool to size, but use the nut and bolt to attach.
