The Science

Why Ceramic
Changes Everything

Silicon nitride (Si₃N₄) ceramic is harder than steel, immune to corrosion, and requires almost no lubrication to spin freely. The result: measurable power savings every single ride.

30% Less Friction

Ceramic balls produce dramatically less rolling resistance than their steel counterparts.

Zero Corrosion

Si₃N₄ ceramic is chemically inert. Rain, salt and sweat have no effect whatsoever.

Lighter Mass

Ceramic is ~30% lighter than steel, reducing rotating weight and improving acceleration.

Thermal Stable

Ceramic maintains its properties across a huge temperature range, from -50°C to 1,000°C.

How We Make Them

01

Raw material selection

We source only pharmaceutical-grade Si₃N₄ powder from ISO-certified suppliers.

02

Hot isostatic pressing

Balls are formed under 2,000 bar at 1,750°C for maximum density and uniformity.

03

Precision grinding

Each ball is ground and polished to ABEC-5 (G25) sphericity and surface finish tolerances.

04

100% inspection

Every single bearing is measured, run-tested and inspected before packing.
