Single-speed and fixie commuters put their chain through relentless daily use in all weather conditions. The KMC Z510RB is engineered specifically for this environment — a 1/8" single-speed chain with a dedicated anti-rust coating that holds up to urban riding, wet weather, and the grime that accumulates on a daily commuter.

• Anti-rust (RB) coating provides superior corrosion protection over standard single-speed chains
• 1/2" x 1/8" pitch for single-speed, fixed-gear, and track bikes with 1/8" drivetrain components
• 112 links per chain — standard length for most single-speed builds
• Grey finish for a subtle, practical appearance
• Workshop box of 25 chains for high-volume servicing of commuter and rental fleets

The RB (Rust Buster) treatment in the Z510RB is a step above the standard Z510 — making it the preferred choice for any bike that lives outside or sees regular wet-weather use. The 1/8" width suits track-style hubs, BMX freewheels, and standard single-speed rear wheels.

Fits single-speed, fixed-gear, and track bikes using 1/8" chainrings and sprockets. Not compatible with multi-speed cassette drivetrains.
