🚴… High-Power Responsiveness & Lateral Stiffness
Under high power output, the wheelset responds efficiently, maintaining noticeable   lateral stiffness despite its lightweight design.

🚴… Gunmetal Titanium Alloy Spoke Nipples
Anti-loosening treatment applied on low-tension sides for enhanced long-term   stability.

🚴… Freehub Body with Ratchet Structure
Four-pawl, dual-tooth engagement design delivers 180–200 Nm torque capacity,   tested for 100,000 cycles without damage.

🚴… UPVINE Custom Bearings
Precision grade P5, vibration grade Z2, radial clearance 7–11 μm, combined with   SRH grease for smooth and durable performance.

🚴… Dedicated in-house hub factory
Designed, engineered, and manufactured in Upvine’s own hub factory with over 10   years of expertise.

🚴… Exceptional Climbing Performance
With a total weight under 1000g, the Ultra wheelset significantly reduces rotational mass, making climbs feel noticeably lighter and more efficient.

🚴… 60T Conical Ratchet System
Equipped with a 60T conical ratchet mechanism, reducing engagement angle compared to conventional ratchet systems, delivering faster power engagement and sharper drivetrain response.

🚴… Custom Ultra-Light Hub Construction
Manufactured from aerospace-grade materials derived from the same material family used in the C919 program, ensuring high strength-to-weight performance.

🚴… Asymmetric Rim Design
The asymmetric rim geometry balances spoke tension between both sides, improving overall wheel stiffness, stability, and long-term durability.
