How to Fix a Bike Chain (Without Stressing About It)

It always happens at the worst time—you’re halfway up Bliss Road, cruising the La Crosse River Trail, or just trying to get to class, and suddenly your chain slips or snaps. Don’t panic. Fixing a bike chain is easier than it looks, and once you’ve done it a couple of times, it becomes second nature.

Here’s what to do the next time your ride comes to an unexpected stop.

If the Chain Just Slipped Off

This is the most common issue and takes less than a minute to fix.

1. Shift into the smallest chainring in the front and back.

2. Place the chain back onto the front chainring with your hand.

3. Pedal slowly to reset it on the gears.

Tip: Always check that your derailleur is aligned—if it keeps happening, something may be bent or loose.

If the Chain Breaks

A snapped chain looks scarier, but it’s still manageable with the right tools.

1. Carry a small chain tool and a quick link in your bag.

2. Use the tool to remove the broken link.

3. Reconnect the chain with the quick link.

4. Spin the pedals to make sure it runs smoothly.

This repair takes five minutes once you know what you’re doing.

Pro Tips for La Crosse Riders

• Carry a mini tool kit: Tire levers, multi-tool, and a quick link can save your ride.

• Keep your chain clean and lubed: Dust and grit from the Driftless trails wear chains faster.

• Check chain wear regularly: If your chain is skipping or slipping often, it might be stretched and due for replacement.

You don’t need to be a pro mechanic—just a little prep makes a big difference.
