HSC Ceramic Derailleur Pulleys
| Availability: | In stock |
HSC Ceramic Jockey Wheels upgrade one of the most frequently rotating components in the drivetrain with low-friction ceramic bearing technology. Pulley wheels spin constantly while pedaling, making bearing quality a meaningful factor in drivetrain efficiency and long-term durability.
HSC has supplied high-quality ceramic bearing solutions to the cycling industry for years. These jockey wheels combine lightweight pulley bodies with precision ceramic bearing assemblies to reduce rolling resistance, improve longevity, and maintain consistent drivetrain performance across modern road drivetrains.
Pulley Construction Options
HSC offers several pulley constructions so riders can choose the balance of weight, cost, and performance that best fits their build.
- Full Ceramic Carbon — carbon pulley body paired with full ceramic bearings using zirconia races and silicon nitride balls for the lowest friction and lightest system weight.
- Carbon Hybrid Ceramic — lightweight carbon pulley body combined with hybrid ceramic bearings featuring silicon nitride balls with hardened steel races.
- Delrin Hybrid Ceramic — injection molded Delrin pulley body with the same hybrid ceramic bearing system for durability and lower cost.
Why Ceramic Pulley Bearings
Ceramic bearings provide several advantages in high-speed rotating components like derailleur pulleys, where reduced drag and consistent bearing performance contribute to drivetrain efficiency.
- Grade 3 silicon nitride (Si3N4) ceramic balls
- Reduced rolling resistance compared to standard steel bearings
- Lower thermal expansion under load
- Improved wear resistance and longevity
- Low-friction seals for consistent operation
- Optimized for high rotation drivetrain components
Product Details
Pairs Well With
For additional drivetrain efficiency upgrades, ceramic pulley systems are commonly paired with low-friction chains and ceramic bottom bracket bearings. Riders building high-efficiency drivetrains may also consider components like the Extralite UltraPulley or lightweight ceramic bottom bracket systems.
