I snapped my chain tonight for the first time but managed to fix it luckily with the special tool.

I'm planning to go cycling over the weekend and can't be arsed to go to the bike shop and get a new chain. Can I go riding with my chain like it is or will something bad happen? It felt fine for the remainder of my ride this evening.

Cheers.

If it was the correct length before, and you removed a link, then it'll be too short now. A big / big gearing combination will lock everything up and break things - generally rear derailleurs.

TBH the last time I had a chain break on me, it was totally mullered and I had to fit an entire new drivetrain.

Well just how did you mend it with a special tool? ๐Ÿ˜†
probably best to pick up a power link or three from your shop and fix it properly.

No, I mean a new drivetrain.

The chain had worn to the point that the chainrings and cassette were heavily worn too. Fitting a new chain just wears out the new one in short order, as it doesn't mesh properly with the worn kit still on the bike.

My experience is that chains break if you've put them back together poorly, or if they're badly worn. That said, I've only ever known three chains break - one on my bike, two on friend's.

depends, if you took all of the bent bits out it should be OK if you can still get the full range of gears. or if you trust yourself not to put it into a gear combination you dont have enough chain for!

tron has point though, they tend to break when they are worn out

I'd just been doing a downhill bit and started pedalling when there was a crunch as there often is and the chain snapped.

I removed 2 links using the punch and reconnected the chain and it got me through the rest of the ride fine. Haven't a clue if I did it right.

you should be able to see if it is straight and nice and it will make a nasty clacking noise if not. check if you have any stiff links though. I've run on fixed chains for months and months in the past. it will annoy the hell out of you if it lets you down in the middle of nowhere though

I've got the same problem. Mullered a complete link (inner and outer) and had to join it back together to get home.

I have spare links from when I shortened it but not sure if I should:

A) re-break the chain where I have disturbed the rivets already and insert a new link from the spare.

B) leave the bit I fixed on the ride and add a new link next to the master link

C) re-break the bit I fixed on the ride and add return the chain to the original length (large + large + 1 whole link) using 2 master links so there are no rivets that have been disturbed.

(C) is the safest I guess but will try (A) for now and remember to carry my spare master links this time.

It depends on the chain. I mangled a 10spd Ultegra chain last week after around 100 miles of use, and putting it back together didn't work due to the rivet design. On the other hand, I've fixed plenty of cheapie 9spd SRAM chains with no issues.
