Relinking chain on 24 speed

Hey, so fitted a new derailleur to my mates bike as the old one had a worn away nub that held it in place.

It's one symptom of many on this bike, needs a few other bits replacing too.

Anyway, I watched a video on using a chain breaker, which just suggested pushing back in the existing rivet after you have done the work. I discovered on a ride today how temporary this is supposed to be as the chain broke.

So I'm just looking to repair the chain for now until it goes in for service next Wednesday, but I'm a bit confused as to what I need to fix it.

I was looking at the speed links, but they dont seem to exist for a 24 speed chain (3 front, 8 rear) - no problem if I cant buy one of these but if so what do I need to repair the chain?

    The chain is an 8 speed chain - which differs by an n speed chain by its width. All 8 speed chains are the same. You can re-assemble the chain but you need a special 'rivet' which is longer and snaps off. Better is to go to Halfords and get a quick link for an 8 speed chain - you don't need any rivets.
    ...take your pickelf on your holibobs.... :D

    jeez :roll:

    Lovely, I was beginning to suspect that the 'speed' of the chain must be defined by the rear cassette - thanks for confirming.

    You can get quick links, but they are usually labelled as 7 speed which are the same part as for an 8 (same chain width).

    ?

    Generally modern bike chains have the pins swaged over, ie flattened, so it stops them coming out.

    When you push the pin, you reshape the end so chances are when pushed back, it is likely to fall.


    With shimano chains, there is a special pin that should be used or as has been mentioned, a quick link.

    The old fashioned way would be to swage the end of the pin.
