There are many reasons why you’ll need to replace a bike chain.
Maybe you’ve worn your chain down from excessive use, and now it won’t fit well on the sprocket.
Or it might be because the chain is too rusted-over after being left locked up outside in the rain.
Or…you might have just ridden a bit too hard, and the chain simply snapped from the stress of that killer trick you finally mastered.
Whatever the reason, you’re trying to figure out how to replace a bike chain so you can get back out on the road. Synergy BMX | Skate | Scooter Shop has the tips you need to know to get your BMX back in gear!
First, pick up a chain breaker from Synergy’s BMX Shop in Prospect Park. Align the pin from the chain breaker with one of the intact pins on your chain.
Then, all you do is turn. Keep turning the chain breaker until the pin is lined up with the top part of the link…but don’t push the pin all the way out! (putting the pin back is EXTREMELY difficult…you don’t want to completely remove it!)
The section of the link that still has the pin in it is now called the “male”, which makes the other part the “female”. Gently pull the male and female parts of the link apart, until the chain is separated. Then, remove the chain from the frame.
To reassemble the chain, align the male and female parts of the link, making sure that the pin is lined up with the hole in both parts of the link.
Pick up your chain break, and reconnect it to the link, turning until the chain pin is completely back in both parts of the link.
To make this process easier, we’ve included a few photos below which should help guide you through the basics of how to replace a bike chain.
