YBN REINFORCED Chain 1/2x1/8x 102-HalfLink 1-Speed Freestyle Bike

YBN MK918 Reinforced Half-Link Chain 1/2 x 1/8 Chrome 102 Links Single Speed BMX Cruiser.

The YBN MK918 half-link chain is a strong, reliable chain made for single-speed bikes where proper chain tension and durability really matter. The half-link design makes it much easier to dial in the perfect fit compared to a standard chain.

This chain is a great choice for BMX freestyle, single-speed cruisers, fixed-gear bikes, and custom builds, especially if you want both performance and a clean chrome look.

• Half-link design allows more precise chain length adjustment

• Reinforced steel construction for strength and long life

• Includes a bullet-style master link for easy installation and removal

• Chrome finish looks great and helps resist surface rust

• Ideal for BMX, cruisers, fixed gear, and custom builds

A normal chain only adjusts in full-link steps, which can make it hard to get the tension just right. A half-link chain lets you fine-tune the length more precisely so you can:

• Get better chain tension

• Avoid awkward wheel positioning

• Often skip using a chain tensioner

• Enjoy smoother pedaling and less wear

This is especially helpful on BMX and single-speed bikes.

Works with:

• Single-speed BMX bikes

• Single-speed cruisers and lowriders

• Fixed-gear and track bikes

Your bike must use:

• A 1/8″ chainring

• A 1/8″ rear sprocket

Does NOT work with:

• Multi-speed bikes (6–12 speed)

• 3/32″ drivetrains

• Bikes with derailleurs

Simple rule:
Wide 1/8″ sprocket = ✔ correct chain
Narrow 3/32″ sprocket = ✖ not compatible

• Bullet-style master link included

• Makes installing or removing the chain much easier

• Secure connection designed for single-speed use

• Chrome look for clean or show builds

• Matches chrome rims, chainrings, and other polished parts

• More corrosion-resistant than uncoated steel

• Comes with 102 links and may need to be shortened to fit your bike

• A chain tool may be required for sizing

• Set chain tension properly — not too tight, not too loose

Tip:
A properly adjusted chain should have a small amount of up-and-down movement.
