3 Problems These Caps Solve Instantly:
-
Don't Let Chain Grease Ruin Another Outfit
Nothing ruins a ride faster than grease on your jeans. These caps keep your chain covered and your look clean, so you can ride out without the mess.
-
Freedom & Expression
There’s something powerful about creating a bike that’s fully yours. These caps turn a regular ride into a reflection of your style -bold, different, and impossible to ignore.
-
Make Your Bike Feel Brand New Again
You don’t need a new bike to feel that new-bike excitement. With a fresh chain setup, your old ride comes back to life - brighter, cleaner, and full of personality.
Fits Most Single Speed Bikes (bikes without gears)
Our caps are engineered for standard 1/2" x 1/8" chains found on most kids' single speed bikes.
They snap on in minutes, stay secure for years, and cover just 3 sides of each chain link - leaving the bottom open for easy cleaning and maintenance.
Patented Design Trusted by Bike Manufacturers & Pro Riders
Our caps (U.S. Patent #7571595) snap on by hand in seconds, block messy grease from clothes, and stay locked tight through ramps, tricks, and everyday adventures - no tools required, just professional results.
