Features:
Conquer conditions, not just courses. Built for riders who don’t let weather or terrain dictate their schedule, our Hybrid Ceramic Bearings are the cornerstone of a dependable bike. They combine battle-ready sealing with a wear-defying ceramic core, ensuring buttery-smooth, silent performance ride after ride, regardless of what the road or trail delivers.
Built to Endure:
✅ Sealed for the Real World
The 2RS double-seal system is your first line of defense. It’s meticulously engineered to block out mud, slurry, abrasive dust, and corrosive road salts, trapping high-grade lubricant inside for the long haul.
✅ The Indestructible Core: Si3N4 Ceramic
Unlike steel, these ceramic balls cannot rust or corrode. Their extreme hardness makes them highly resistant to brinelling (dent marks) from impacts and pitting from contaminants, which are the primary killers of bearing smoothness.
✅ Dual-Material Resilience
The high-precision steel races provide robust structural support, handling shock loads, while the ceramic balls handle the rotation with minimal wear. This synergy guarantees durability where it counts.
Ride With Unshakable Confidence:
🛡️ All-Weather, All-Terrain Ready – Push through puddles and dust storms with zero compromise. Your bearing performance remains constant, eliminating a key variable from your mechanical concerns.
🔧 Maintenance Intervals, Not Surprises – Dramatically extend service life. Enjoy more time riding and less time worrying about premature wear or costly component replacements.
🤫 Quiet That Lasts – Stop the dreaded "gritty creak" before it starts. The sealed, low-wear design maintains its whisper-quiet operation far longer than standard bearings.
⚡ Consistent Efficiency – Experience the same effortless spin on mile 1,000 as on mile 1. There’s no gradual degradation of performance—just reliable, low-friction operation.
