Ybn Mk918n 3/32" Chain

YBN MK918N 3/32" Chain

Product Overview

The YBN MK918N is a durable narrow 3/32" half-link chain designed for single-speed BMX and fixed-gear drivetrains. Featuring reinforced plates with improved tensile strength (1400kgf), it allows precise chain tension adjustment through half-link removal and includes a pin for easy installation.

Key Features

• Half-Link Design – Removable half-links enable fine-tuned chain tension adjustment without removing full links; critical for single-speed precision
• Heavy-Duty Construction – Reinforced, thicker plates provide superior strength and durability under high tension constraints
• Improved Tensile Strength – 1400kgf rating resists stretching and breaking during aggressive racing and tricks
• Narrow 3/32" Profile – Compatible with single-speed cogs and chainrings; standard BMX chain width
• 96 Links – Adequate length for most BMX frame geometries; adjustable via half-link removal
• Pin Included – Master link pin included for straightforward chain installation and removal
• Single-Speed Optimized – Purpose-built for high-tension single-speed transmissions without derailleurs
• Professional Racing Component – Engineered for BMX racing and fixed-gear performance demands

Compatibility & Ideal Use Cases

• Single-speed BMX drivetrains – Half-link design optimized for single-speed tension requirements
• Fixed-gear setups – Precise tension adjustment critical for fixed-gear performance
• High-tension applications – 1400kgf tensile strength resists stretching under aggressive racing
• 3/32" cog and chainring compatibility – Works with standard single-speed BMX components
• Racing and freestyle – Suitable for all BMX disciplines requiring single-speed drivetrains
• Precise chain tensioning – Half-link removal allows fine-tuned tension without full-link gaps
• Professional riders – Heavy-duty construction suitable for competitive racing applications
• All rider types – Durable design accommodates beginners through advanced riders

Build Requirements & Compatibility

• 3/32" Chainring and Cog – Compatible with standard single-speed BMX chainrings and cogs (verify sizing)
• Chain Length Adjustment – Remove half-links as needed for precise fit to your drivetrain
• Master Link Installation – Use included pin for quick chain installation and removal
• Chain Tensioner System – Works with standard BMX chain tensioners for proper alignment
• Spoke Guard Clearance – Verify adequate clearance between chain and rear wheel spokes

Important Notes

• Half-link design essential for single-speed BMX; full-link chains lack precision needed for tension adjustment
• 96 links provide standard length; adjust via half-link removal based on your frame geometry
• Master link pin included; no additional hardware required for installation
• Reinforced plate construction resists wear and stretching under high single-speed tension
• 1400kgf tensile strength rated for professional racing demands
• Heavy-duty construction optimized for BMX racing; not suitable for casual, minimal-maintenance applications
• Precise chain tension critical for single-speed performance; use half-link design to achieve optimal adjustment
• Compatible with standard 3/32" BMX cogs and chainrings
