You know you're having a bad day when.....

..... you stupidly break your new chain too short and end up ordering another one

Try this...

1. ) Measure the distance between the rear wheel scewer and the center of your cranks. Round off to nearest 1/8 inch. Take that value and double it.
2.) Divide the count of the number of teeth on the large chain ring by 4.
3.) Divide the count of the number of teeth on the biggest cog on your cassette by 4.
4. Add the values from steps 1+2+3 and add 1 inch more to the total.

That's the length in inches that your road bike chain should be.

I used the number of the links in the old chain for the length of the new one. In my haste, I miscounted and marked the breakage point in the wrong place.

I'll pay more attention on the next one lol.

You could have successfully rejoined the chain, then separated it at another point.

Use the chain-breaker to put the rivet back in. I do that all the time. I never use joining links. When you break a chain, never push the rivet all the way out. Push it just far enough to clear the inner link. That makes it easier to push it back in.

Thanks for the suggestions, but I'm kinda finicky about stuff like this, so I'd rather use a new chain.

Crazy...... Yes I am

I've just changed from 42t to 46t rear cassette so old chain length was no use. Before starting take a photo of derailluer angle when in lowest gear and highest gears old cassette) before starting. Also see Youtube videos.

It's really fun trying to align a rivet which has come all the way out. .. much easier to just give up and add on a few links from another chain and then substract if necessary.
Chain breakers are cheap, and work very well .10 euro . provided you don't let a rivet escape... Practice on the old chain first.

If you push the rivet all the way out, you can use one of these:

You take the front wheel out of your folder and lean it on the rear bumper while you load the Folder into the Estate...close the lid...hop in the driving seat and reverse over the wheel. What's even worse that the bike isn't mine I was just repairing it for a friend....sigh...£80 for a new one.
