Chain Fixed Gear – Blue & Yellow Two Tone Insane Chains

A chain fixed gear setup is built for style and simplicity — and Insane Chains make it unforgettable. With Blue & Yellow Two Tone snap-on caps, you can transform a plain metal chain into a custom feature that gets attention at the track, in the park, or on the street. The bright mix of yellow and blue creates a high-energy look that stands out in any crowd.

Each box includes 56 pieces sized for fixed gear and single-speed bikes 16 inch and larger. Shopping for a kids bike 14 inch and under? Choose the 35-piece size instead. Both options are made to fit 1/2" x 1/8" chains, so they’ll work on BMX, SE Bikes, cruisers, e-bikes, and fixies.

Installation is quick and hassle-free: line up a cap with a chain link, press until it clicks, and repeat. No tools required, no grease on your hands, just a bold new chain style in minutes.

Insane Chains do more than look good. They also protect your clothes from messy chain grease, keeping your jeans, shorts, and sneakers clean. Riders love the custom look, parents love the practicality, and everyone notices the difference.

If you want to upgrade your chain fixed gear ride with color and confidence, the Blue & Yellow Two Tone Insane Chains are the perfect choice.
