Beta Testing Now Underway – Speed-Focused Riders Wanted
Born from a singular mission—to make the fastest wheels even faster—Cycco ULTRALIGHT sealant is engineered to minimize rotational mass without compromising real-world puncture protection. By dramatically reducing sealant density, this formula allows your wheels to spin up faster, accelerate harder, and maintain speed with less resistance.
Unlike conventional sealants that add unnecessary weight, Cycco ULTRALIGHT uses an advanced low-density particle system that stays mobile inside the tire, instantly migrating to punctures while maintaining the lightest possible spinning mass.
This is not just a lighter sealant—it’s a completely different performance category.
Key Features:
✅ World’s Lowest Rotational Mass – Engineered for the lightest possible spinning weight
✅ Faster Acceleration – Reduced internal mass improves responsiveness and speed
✅ Competitive Puncture Protection – Seals typical road, gravel, and MTB punctures up to 3–4mm
✅ Advanced Particle Suspension – Precision-engineered sealing particles rapidly bridge and close punctures
✅ Ultra-Low Density Formula – Dramatically lighter than traditional latex-heavy sealants
✅ Speed-Optimized Performance – Designed specifically for performance road, gravel, and race applications
✅ CO2 Compatible – Fully compatible with CO2 inflation systems
✅ All-Temperature Performance – Reliable sealing across extreme temperature ranges
✅ Safe for All Wheel Types – Carbon-safe, rim-safe, and tire-safe formula
IMPORTANT PROTOTYPE NOTE:
This formula may show visible separation or “creaming” when sitting unused. This is normal and expected for ultra-low-density systems. Simply shake thoroughly before installation to restore optimal performance. This separation is a visual indicator of the advanced lightweight particle system—not a defect.
WHAT MAKES IT DIFFERENT:
Traditional sealants prioritize maximum sealing at the cost of added weight. Cycco ULTRALIGHT was engineered from the ground up to minimize rotational inertia while still delivering dependable real-world puncture protection. The proprietary low-density sealing system allows rapid particle movement and efficient puncture sealing with significantly less mass inside your tire.
The result: faster wheels, quicker acceleration, and a noticeably lighter ride feel.
EARLY ADOPTER BENEFITS:
Submit feedback through our website form and receive:
• Priority access to future production releases
• 50% off your next purchase
• Direct input on formula refinement
• Exclusive beta tester status
Early adopters also get their choice of any of our road bike bar plugs for free!
THE PROTOTYPE PROMISE:
This is an early prototype release intended for real-world validation by performance-focused riders. Your feedback directly influences final production. We actively ride and test this formula ourselves, but real rider input is essential to refining the world’s fastest sealant.
ENVIRONMENTALLY CONSCIOUS:
• Non-toxic formula
• Biodegradable base components
• Latex-free and allergy-friendly
• Safe for carbon rims and high-end wheelsets
RECOMMENDED AMOUNTS:
🚴 ROAD BIKES
23–25mm tires: 1 oz (30ml)
28–32mm tires: 1.5 oz (45ml)
🚴♂️ GRAVEL
35–45mm tires: 1.5–2 oz (45–60ml)
🚵 MOUNTAIN BIKES
2.0–2.3" tires: 2 oz (60ml+)
2.4–2.6" tires: 2–2.5 oz (60–75ml+)
Lower volumes can be used due to enhanced particle efficiency and reduced density.
INSTALLATION METHODS:
METHOD 1: THROUGH VALVE STEM (PREFERRED)
Remove valve core
Shake bottle thoroughly (very important)
Inject recommended amount
Reinstall valve core
Inflate tire
Spin and shake wheel to distribute
METHOD 2: TIRE BEAD METHOD
Break bead on one side
Shake bottle thoroughly
Pour recommended amount into tire
Reseat bead and inflate
Spin and shake wheel
PROTOTYPE PERFORMANCE FOCUS:
This formula prioritizes speed, efficiency, and minimal rotational weight. It is ideal for riders seeking maximum performance gains from reduced spinning mass while maintaining dependable puncture protection.
Ride faster. Spin lighter. Test the future.
