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.
Ceramic vs Steel
How We Make Them
Raw material selection
We source only pharmaceutical-grade Si₃N₄ powder from ISO-certified suppliers.
Hot isostatic pressing
Balls are formed under 2,000 bar at 1,750°C for maximum density and uniformity.
Precision grinding
Each ball is ground and polished to ABEC-5 (G25) sphericity and surface finish tolerances.
100% inspection
Every single bearing is measured, run-tested and inspected before packing.
