Where You’ll Feel the Revolution:
The Unfair Advantage:
Your Power Transfer Just Got a Quantum Leap
Stop leaking watts to friction. Engineered for racers and obsessives, these 2RS double-sealed Hybrid Ceramic Bearings eliminate hidden drag in your drivetrain’s critical junctions. Silicon Nitride (Si3N4) balls glide silently against precision steel races, transforming sluggish rotation into explosive acceleration – where every pedal stroke actually becomes forward motion.
Why Elite Riders Demand This Tech:
🔥 Friction Vaporized: Ceramic balls cut rotational resistance by up to 50% vs. steel. Feel instant responsiveness climbing hills or sprinting.
🛡️ 2RS Mud Armor: Dual rubber seals lock out trail grit, river crossings, and winter slush – no compromised performance when conditions turn savage.
⚡️ Zero Corrosion, Zero Compromise: Si3N4 balls laugh at rain, salt, and chain lube splash. Ride through monsoons without rust-induced drag.
🔇 Silent Power Delivery: Eliminate creaks in bottom brackets and hub whine. Hear only the wind – not your bearings fighting you.
Where You’ll Feel the Revolution:
• Bottom Brackets: Convert mushy pedal feel into razor-sharp power transfer. No more "dead spots" or mysterious creaks stealing efficiency.
• Rear Hubs: Harvest every ounce of energy from your drivetrain. Wheels spin up faster and hold speed longer – critical when fatigue sets in.
• Headsets & Pivots: Achieve telepathic steering precision and suspension that reacts, not resists.
The Unfair Advantage:
"It’s not an upgrade – it’s removing a speed tax."
Pre-lubed with synthetic racing grease, these bearings deliver immediate performance gains from mile one. Cyclists report:
✓ Faster sprints with less perceived effort
✓ Longer service intervals – even in brutal conditions
✓ Weight savings where rotational mass matters most
