YBN MK918 1/8" Half-Link Chain

Overview

The YBN MK918 is a heavy-duty 1/8" single-speed chain with half-link construction designed for high-tension applications like BMX and fixed-gear bikes. Reinforced plates and superior tensile strength provide durability and reliability under the demands of tricks, jumps, and consistent power transfer.

Key Features

• Half-Link Design — Half-links enable precise chain tension adjustment by removing increments smaller than full links; critical for single-speed bikes where exact tension directly affects performance and component life
• Reinforced Heavy-Duty Plates — Thicker, stronger chain plates resist bending and breaking under high loads and repetitive impact from tricks and jumps
• 1400kgf Tensile Strength — High tensile rating handles extreme tension loads common in BMX and fixie applications without stretching or snapping
• Wide 1/8" Profile — Standard single-speed chain width ensures compatibility with all 1/8" sprockets and cogs
• Pin Included — Connector pin supplied for tool-free assembly; allows quick chain joining without additional hardware

Technical Specifications

Compatibility & Ideal Use Cases

Compatible with all single-speed BMX frames, fixed-gear bikes, and cruisers using 1/8" sprockets. The half-link design is essential for riders who need precise chain tension adjustment without the guesswork of full-link removal. Ideal for street, park, and trick riding where chain durability and consistent tension under high loads are critical. Also suitable for fixed-gear riders requiring reliability during acceleration and braking.
