BMX Bikes Used or New - Upgrade with Purple Snap-On Chain Caps

BMX bikes used or new deserve a fresh look, and nothing upgrades a chain faster than Insane Chains Purple snap-on caps. With their deep, bold color, these caps turn a standard chain into a custom detail that makes your bike stand out. Whether you’re giving new life to an older ride or customizing your latest build, purple brings a sharp, eye-catching finish that gets noticed at the park, on the street, or at rideouts.

Each pack is designed for 1/2" x 1/8" single-speed chains. Choose 56 pieces for bikes 16 inch and larger, or 35 pieces for kids’ bikes 14 inch and under. Installation is quick and easy: line up a cap with a chain link, press until it clicks, and repeat. In minutes, your chain goes from plain to insane — no tools, no grease, no stress.

Insane Chains aren’t just about color. They also protect your clothes from chain grease, keeping jeans, sneakers, and shorts clean while you ride. Parents appreciate the practicality, while teens and adults love the attention that comes with a bike that looks fresh, no matter its age.

If you want BMX bikes used or new to stand out with a custom chain upgrade, Purple Insane Chains are the perfect choice.
