Why Having a Chain Breaker on Your Multi-tool Is Essential

I once knew a guy who thought he was invincible. Rode his gravel bike everywhere, through mud, over rocks, into places where the sun forgot to shine.

He had legs like tree trunks and lungs like a furnace, but he didn’t have a chain breaker.

One day, deep in the woods, his chain snapped. No chain breaker. No quick link. No way out except a long, humiliating walk back to civilization.

That guy? Yeah, that was me.

Let’s talk about why you need a chain breaker. Because one day, when you least expect it, you’re going to wish you had one.

1. Chains Break When You Least Expect It

The gods of cycling don’t break chains when you’re coasting downhill in front of a café. No, they wait until you’re deep in the wilderness, miles from help, legs burning, with a storm rolling in. If you don’t have a chain breaker, you’re not riding home—you’re walking.

2. Gravel and Trail Riding Are a Different Beast

Fixed-gear riders don’t worry about chain breakers much. Their chains are thicker, burlier, built like an old truck. But a gravel bike? A mountain bike? Those dainty, multi-geared chains are like a rich kid’s trust fund—impressive but fragile. One bad shift, one unlucky rock, and SNAP.

3. It’s Not Just for You

Think you’re special? Think you’re immune? Fine. Maybe you never break a chain. But what about your riding buddies? The guy struggling up the climb, the woman who misjudged a shift? A chain breaker isn’t just a tool—it’s a rescue device. I once saved a guy mid-ride by turning his broken derailleur disaster into a single-speed miracle. He rode 70 km home on a jury-rigged setup, grinning like a madman.

4. A Quick Link Is Useless Without It

Carrying a spare quick link is smart. But guess what? You can’t use it if you can’t remove the broken section of your chain. A chain breaker is the key to making that spare link actually work. Otherwise, you’re just carrying tiny bits of metal for fun.

5. It’s a Rare Need, but an Essential One

In 80,000 km of riding, you might only need a chain breaker once. But that one time will be the difference between riding home and pushing your bike for miles like a lost pilgrim. It’s like home insurance—you don’t need it until you really need it.

6. Bikepacking? You Better Have One

If your idea of a ride is a 20-minute loop near a bike shop, fine, gamble with fate. But if you’re riding 100 km into the backcountry, where the nearest mechanic is a grizzly bear, you need to be self-sufficient. A broken chain on a multi-day ride isn’t just an inconvenience—it’s the end of your trip.

7. Multi-tools with Chain Breakers Exist for a Reason

Manufacturers don’t throw chain breakers onto multi-tools just for decoration. They know the truth: a chain breaker is an essential piece of survival gear. If a mechanic, a seasoned bikepacker, and a random stranger on the internet all tell you the same thing, maybe—just maybe—they’re onto something.

Summary Table: Why You Need a Chain Breaker

Reason	Why It Matters
Chains break unpredictably	They snap when you’re far from help.
Thin chains break easier	Gravel and MTB chains are weaker than fixed-gear chains.
It’s useful for helping others	You might not need it, but someone else will.
Quick links need a chain breaker	You can’t install a quick link without removing a damaged section.
It’s rare but critical	One failure in 80,000 km is still enough to ruin a ride.
Essential for remote riding	No bike shops in the wilderness.
Multi-tool makers include it for a reason	It’s not just extra weight—it’s a necessity.

Some people will argue they’ve never needed a chain breaker. Those people are lucky. Luck is nice, but it’s a bad survival strategy.

You can ride 10,000 km without a problem, then on ride 10,001—SNAP—you’re stranded. You’ll stand there, staring at your useless hunk of metal, wishing you had listened.

Carry a chain breaker. One day, it’ll save your ride. Or someone else’s. Or maybe your dignity.

And if you think you don’t need one?

I hope you like walking.
