KMC S1 RB 1s Chain for Urban Cycling & BMX

Elevate your ride with the KMC S1 RB Chain, the ultimate workhorse for single-speed bicycles. Engineered for reliability and durability, this 1s chain is the perfect choice for the demands of Urban Cycling, BMX, Track, and Fixed Gear riding. Whether you´re navigating busy city streets, landing tricks at the skatepark, or pushing for a personal best on the velodrome, the S1 RB is built to perform consistently, day in and day out.

Unmatched All-Weather Durability

One of the standout benefits of the KMC S1 RB is its exceptional resistance to the elements. Featuring KMC´s proprietary Rust Buster (RB) coating, this chain is meticulously treated to provide a powerful barrier against corrosion. Ride with confidence through rain, humidity, and road spray, knowing that your chain is protected from the rust that can degrade performance and shorten a component´s lifespan. This anti-rust feature not only ensures a longer-lasting chain but also significantly reduces maintenance, allowing you to spend more time riding and less time cleaning.

Smooth, Quiet, and Efficient Performance

Experience a noticeably smoother and quieter drivetrain thanks to the S1 RB´s modern bushingless construction. This advanced design reduces friction and operational noise, resulting in more efficient power transfer from your pedals to the rear wheel. Every pedal stroke feels more direct and responsive, providing a superior riding experience compared to traditional chains. Its robust build is specifically designed to handle the high-torque demands of single-speed acceleration, fixed-gear skids, and powerful BMX starts, ensuring it won´t stretch or fail when you need it most. The inner plates are also specially shaped to prevent chain drop, giving you an extra layer of security and reliability on any terrain.

Versatility for Your Single-Speed Setup

The KMC S1 RB is a highly versatile chain designed to be the go-to solution for a wide array of 1s drivetrains. Its 1/2" x 1/8" sizing makes it the industry standard for single-speed applications. It is fully compatible with standard single-speed freewheels, bicycles with integrated gear hubs, BMX bikes, track machines, and fixed-gear builds. With 112 links, it provides ample length for most standard setups, and it can be easily shortened to achieve the perfect tension for your specific bike.
