Breaking a Chain w/o Chainbreaker

First post!
I have an old bike that I want to take the chain off. I did not find a master link or anything. I just want to get the chain off by any means possible, as I'm just going to throw it away afterwards.

Any ideas?

Well, I imagine you could just use bolt cutters

You might just buy a Chain Breaker.

Why?

When you get a new chain you might have to remove some of the links to get a proper fit.

1/8" or 3 mm drift punch and a hammer to drive out a pin.

One person on today's ride managed to remove his chain without using any tools at all. Getting it back together was a little more work and did require use of a chain tool.

But I'd expect that if you're not concerned about reusing the chain then just twisting it back and forth sideways would open up one of the links before long.

+1. Plus you'll need it to drive the pin when installing a new chain.

Well worth the investment.

Unless a master link is used.
Of course, a tool would be needed if the chain is too long. As previously mentioned.

Small investment, as bike tools go.

$5 - $10 spend it or just do any one of the hacks above it will come off.

+10 Bolt cutters, that's what I use on nasty, rusty chains. Broke my old chain tool trying to force a pin on a POS chain. No more.

As others point out, you'll need a chain tool to cut the next chain to size so you might as well go for it now. But if you just want to get it apart for now, fit 2 screwdrivers into the spaces between two adjacent outer links, and twist them in opposite directions.

Remember this is only for chains headed to the scrap heap.

Get two large rocks:
1. Lay chain across one rock.
2. Pound chain with second rock until it separates.

Or just buy a tool you are going to need anyway.
