Features:
 
Forged in the pursuit of marginal gains, this sealed bearing—featuring a stealth grey seal—is dedicated to delivering measurable, efficient performance. It is the calculated upgrade for performance-focused riders who demand verifiable reductions in drag, uncompromised durability, and the concrete advantage of liberated watts at the hub.
 
✅ Aerodynamic by Design for Reduced Drag
Engineered with an ultra-low friction coefficient as its primary target, this bearing is conceived to minimize rotational resistance. Its streamlined internal profile and super-finished components are validated to reduce drag, converting more of your power into propulsive force for a quantifiable sensation of increased speed and efficiency.
✅ Dynamic Seal for Minimal Parasitic Loss
The integrated, low-torque contact seal is dynamically engineered. It provides essential protection against contaminants while actively minimizing the rotational resistance typically associated with sealing, preserving the low-viscosity performance grease and ensuring that efficiency is maintained without compromise.
✅ Race-Proven Materials for Sustained Power Transfer
Utilizing a high-grade nitrogen-treated steel, this unit is proven under sustained power. It is built to handle the heat and stress of prolonged, high-wattage efforts without degradation, ensuring that its efficient characteristics remain constant, providing a platform of reliable, high-performance output.
✅ Precision-Configured for Immediate Results
Supplied as a precision-configured system, this pre-loaded and lubricated cartridge is a direct performance intervention. Its exacting drop-in fit enables a swift and definitive upgrade, yielding an immediate reduction in mechanical resistance and a perceptible lift in overall drivetrain crispness and responsiveness.
 
This bearing is an investment in sustained efficiency and performance clarity. It surgically targets the specific forces that waste energy, contributing to a hub that rotates with minimal inertia, extends component life through reduced heat, and delivers a consistently sharp, efficient, and purpose-built ride quality.
