More than one quick link in a chain - possible?

Is there a limit to the amount of quick links that you can use in a chain - a friend has given me a chain (used for less than 30 miles) that the shop cut down far too short for his bike. Its far too short for my bike, but I was thinking about quick linking a section of spare new chain that I have kicking around to make it long enough to use - this would obviously involve 2 quick links.

Will this be ok or am I looking for trouble?

Thankyou very much

    Not in theory although the more you have the greater the chance of an issue I suppose.

    I know several people with 2 in without any trouble.

    A chain is only as strong as its weakest link. On that basis, it makes no difference how many quick links you have in the chain. If you have no quick links or a chain made entirely of quick links, the strength will be either that of the quick link or the standard link.

    If I didn't trust two, I wouldn't trust one.

    But why use another quick link ? Why not just a normal link?

    Surely the benefit of the quick link is that you can undo it quickly - therefore only 1 required in the chain ...

    But unless there is a marked difference in material/design then I see no reason why you can't have a chain made up of quick links ...

    For 10 speed transmission I suspect cost may be the main barrier to making up a chain from quicklinks. IIRC the 10 speed ones are £8 a pair, so for a 116 link chain that would be £464, plus the initial cost of the chain you'd need to cannibalise to get the inner links / rollers

    Dam! I thought that 2 or 3 links was enough... keef66 have you made a chain from quick links like this:

    Some people want to chain cassettes for different riding and that can leave the chain too short.

    Having a small section of extra chain with a quick link either end means you can lengthen or shorten the chain to suit.

    Cool - thankyou very much.

    I was only going to use 2 quick links so that I could incorporate the new length of chain to the "old" chain easily - one on each end.

    Will have a play and see whats what - thankyou again for the answers though.

    It is not safe to join a 9 or 10sp chain with anything other than a quick link or a joining pin. The original pins are riveted over and this breaks off on removal. Nothing wrong with using 2 quick links.

    I had a chain with two quick links.
    Coming back home from a trip to the Alps, I was breaking the bike down to put in the bike bag for the flight. I wanted to take the rear mech off so the baggage manglers wouldn't break it off and I was going to remove the chain and put it in a polythene bag so I didn't get oily chain everywhere in the bag.
    Couldn't get the damn quick link open and time getting short for the flight...so broke the chain at another pin and fitted another quick link when I got home, ran with two for months until I ended-up replacing the chain in usual way when it got to the wear stage on the chain-checker.

    I suppose if you kept all the offcut links from when you shorten a chain when you fit a new one, plus the old quick links from the chains you replaced, then after about a dozen chains you could join all the offcuts together and make yourself a 'free' chain 8)

    I have 3 quick links in the chain on the recumbent (it does need a chain with about 280 links in it)
    Recipe: shave legs sparingly, rub in embrocation and drizzle with freshly squeezed baby oil.

    I didn't know his. I took a nine speed chain off at the weekend and took out one link, rejoined, then took another as it was still a bit too long. That's probaly two rejoined sites. Are these not safe. Should I bin the chain and start again? I've ridden 80 miles since without obvious problems.

    You may get away with it on a 9sp chain if you have taken care to make sure the pin is right through both plates. The join will not be as strong as a new one. You can not do this with 10sp as the pins are too short.
