The Tripeak #6806 Ceramic Hybrid Bearing (G5) 30x42x7mm is a precision cycling bearing developed for riders and mechanics who want low-friction rotation, accurate fitment and dependable performance in compatible bicycle components. Its hybrid construction combines Grade 5 Si3N4 ceramic balls with precision bearing races, delivering a refined balance of speed, smoothness, durability and practical everyday usability.
Grade 5 Si3N4 Ceramic Balls
At the core of the bearing are Grade 5 silicon nitride (Si3N4) ceramic balls. Silicon nitride is widely used in high-performance bearing applications because it is extremely hard, smooth, lightweight and resistant to deformation.
The use of high-grade ceramic rolling elements helps reduce internal friction and supports efficient rotation, making the bearing well suited to performance-focused road, MTB and racing setups where drivetrain efficiency and smooth component movement matter.
Ceramic Hybrid Construction
Unlike a full-ceramic bearing, the Tripeak 6806 uses a ceramic hybrid configuration. Ceramic balls work in combination with metal bearing races, giving riders many of the rotational benefits of ceramic technology while retaining the structural reliability and familiar installation characteristics of conventional bicycle bearings.
This hybrid approach makes the bearing suitable for cyclists looking for a performance upgrade without moving to a fully ceramic assembly.
Precision 6806 Dimensions
The bearing follows the standard 6806 dimensional format, measuring:
Inner Diameter: 30mm
Outer Diameter: 42mm
Width: 7mm
The precise 30 x 42 x 7mm sizing is essential for correct bearing fit. Before installation, users should verify that their bottom bracket, hub or other cycling component specifically requires a 6806 bearing.
Accurate fitment helps maintain correct alignment, smooth rotation and predictable bearing life.
2RS / LLB Sealing
The Tripeak #6806 features a 2RS (LLB) sealing system, meaning both sides of the bearing are protected by seals designed to reduce contamination from dust, dirt and moisture.
This sealing configuration helps preserve grease inside the bearing while limiting the entry of external contaminants. For bicycles used in changing weather or road conditions, sealed construction provides an important layer of protection against premature wear.
Low-Friction Performance
The smooth ceramic balls and precision internal geometry are designed to reduce rolling resistance within the bearing. Lower friction can help rotating bicycle components move more freely and consistently, contributing to a more refined mechanical feel.
For performance cyclists, this type of upgrade is especially relevant in areas where repeated rotation occurs continuously, such as compatible bottom bracket or hub systems.
Durability and Heat Stability
Si3N4 ceramic balls have excellent hardness and dimensional stability. They are less prone to surface deformation under load than softer materials and perform consistently across a wide operating range.
When combined with proper installation, lubrication and compatible components, this can contribute to reliable long-term bearing performance.
