KMC Z1 EPT Wide 1/8" Chain

Overview

The KMC Z1 EPT is a durable 1/8" single-speed chain with advanced corrosion protection designed for BMX and fixed-gear bikes. EcoProteQ treatment provides enhanced rust resistance while reducing noise and improving overall performance through a smoother coating finish.

Key Features

• EcoProteQ Treatment — Advanced protective coating doubles rust resistance compared to standard rust treatment; provides superior corrosion protection in wet and harsh conditions
• Smoother Coating Finish — Reduced friction and noise during operation; improves shifting smoothness and drivetrain efficiency on single-speed setups
• Anti-Drop Design — Special link geometry prevents chain from falling off sprockets during tricks or sudden deceleration; critical for reliable single-speed performance
• Rust Buster Treatment — Additional corrosion-resistance layer ensures longevity in varied weather and riding conditions
• Wide 1/8" Profile — Standard single-speed chain width ensures compatibility with all 1/8" sprockets and cogs
• 112 Link Count — Mid-range link count accommodates most frame geometries and chainring/sprocket combinations

Technical Specifications
