The Ultimate Single-Speed Chain

Every component has been designed from the ground up to deliver exceptional performance through advanced materials, precision machining, and innovative engineering. CNC machined from aerospace-grade alloys, heat treated, surface engineered, and built to be rebuilt—not replaced—this is a drivetrain component unlike conventional bicycle chains.

Weighing just 205 grams per 100 links, this chain offers an outstanding strength-to-weight ratio, reducing rotating mass for quicker acceleration, improved efficiency, and a more responsive ride.

Aerospace Titanium Construction

Every plate and roller is CNC machined from solid aerospace-grade Ti-6Al-4V titanium. Unlike conventional stamped chain components, each part is individually machined to exacting tolerances before being heat treated and aged to achieve approximately 170,000 psi ultimate tensile strength.

The titanium components are then black nitrided to approximately 70 HRC, producing an exceptionally hard, wear-resistant surface while preserving the strength and toughness of the titanium beneath.

The result is a drivetrain component engineered for exceptional wear resistance, reduced friction, and long-term durability without sacrificing weight.

One of titanium's greatest advantages is its remarkable strength-to-weight ratio. By replacing conventional steel components with precision-machined aerospace titanium, this chain achieves a dramatic reduction in rotating mass while maintaining exceptional structural integrity.

Titanium also forms a naturally protective oxide layer, providing outstanding corrosion resistance. Unlike conventional carbon steel chains, it will not rust when exposed to rain, mud, humidity, or coastal environments, helping maintain both performance and appearance for years.

Maraging 350 Steel Pins

Each pin is precision machined from Maraging 350 steel and heat treated to approximately 350,000 psi ultimate tensile strength before receiving the same black nitriding process to achieve a surface hardness of approximately 70 HRC.

This combination produces an exceptionally strong core with an ultra-hard wear surface capable of withstanding tremendous loads while maintaining excellent toughness.

Maraging 350 steel also provides excellent dimensional stability and superior corrosion resistance compared with conventional high-carbon chain steels. Combined with the black nitrided surface treatment, the pins resist corrosion while delivering exceptional wear resistance for extended service life.

Fully Modular Construction

Unlike traditional bicycle chains that use permanently riveted pins, every pin in this chain is precision threaded.

Any individual link can be removed and replaced in minutes without replacing the entire chain, making servicing simple while dramatically extending the usable life of the chain.

Rather than being a disposable wear item, this chain is engineered to be maintained for years.

Tungsten Disulfide (WS₂) Dry Film Lubrication

Every chain is treated with a burnished tungsten disulfide (WS₂) dry-film lubricant.

Unlike conventional wet lubricants that attract dirt and eventually wash away, WS₂ becomes embedded within the microscopic surface of the metal, creating an extremely low-friction interface between moving components.

The benefits include:

• Extremely low coefficient of friction
• Smoother and more efficient power transfer
• Reduced wear on pins and rollers
• Outstanding performance under extremely high contact pressures
• Cleaner operation by resisting dirt and abrasive contamination
• Longer lubrication intervals than conventional chain lubricants

Because the WS₂ coating remains bonded to the metal surface, it continues providing boundary lubrication even after conventional oils have diminished. Under typical riding conditions, riders can expect hundreds of miles of reduced-friction operation before supplemental lubrication becomes beneficial, although maintenance intervals will always depend on weather, terrain, and riding conditions.
