Snapped Chain

Whilst on a ride today my chain snapped. On closer inspection two outer link plated had bent slightly. Can this be repaired just by reconnecting with a chain link tool or do I need a new chain???

1-How worn is the chain? No sense in putting a worn chain back on.
2-Is there any reason the chain broke? True, outer plates may have been bent slightly, but is that cause, or effect?
3-Are there any other problems with the bike? Like a wheel rubbing, etc.

A new chain is cheap enough. Anything above eight speed and it is not a good idea to connect a chain with a tool, a quicklink should be used (Or a Shimano pin if that is your chain). If the chain has previously been installed using a tool that is probably the source of your problem.

I definitely would not try to repair a damaged link but if the rest of the chain is okay then I would replace the broken link with a suitable quicklink. (The official thinking seems to be that you can only have one quicklink per chain but I can't see the logic in that. If quicklinks were unreliable, yes, you would be doubling your risk, but every broken link I have seen has been a normal one!)

As above check chain and cassette wear. A broken chain normally either comes from extreme wear, a manufacturing defect or how it was fitted.

The chain on my Eastway has two quicklinks in it after I trimmed it too short when I fitted it. :blush: :angry: it's early days yet but so far so good.

Moulton TSR owners will generally have two quick.links - a typical setup with a 56T chainring needs 120 links, which is slightly longer than one new chain!

I've ordered a new quick link. Fingers crossed :okay:

If more than one is no good why would one be ok.
@StuAff of this parish will attest more than one quick link is fine. I wasn't on this particular Fridays ride but his chain 'fell to bits' 3 quick links inserted to join the various bits and all was good.
How long did you ride it like that Stu? Not long I guess.

The rest of the ride. It sounded terrible & shifted badly. Not recommended!

First time I've done it so I'm a doubtful, but as you say there's no reason why it shouldn't work.

Might that be because the quicklinks you (presumably scrounged from fellow riders) used were the 'wrong' speed for your drive train? I fitted a 9sp QL to a fellow rider's parted chain (10sp drive train) which got him home last week from the pub but he'll swap it out for a 10sp QL pronto. His was a Shimano chain and the link he'd pushed the 'new' pin (with break off) into before the ride failed (operator error almost certainly).
