[Pre-order] 9Velo Ultralight Road Disc Carbon Spoke EXTREME C52 Wheelset 20H/20H (23.6 mm inner wide, sub1000 grams)

FEATURES

• The Extreme C52 wheelset weighs in at under 1000 grams (weight of tubeless tape not included), making it one of the lightest deep-section road wheelsets ever produced. This featherweight build translates to fast acceleration and effortless climbing.
• With a 52mm aerodynamic rim depth, the EXTREME C52 strikes a perfect balance between speed and stability. Whether you're pushing hard on flat roads or powering through hill climbs, the deep profile helps you maintain momentum.
• The 23.6mm wide internal rim width supports modern high-volume tires, offering improved grip, lower rolling resistance, and enhanced comfort. It’s fully compatible with both clincher and tubeless setups, offering tire selection flexibility across road conditions and accommodating different riding styles and preferences.
• The rim uses a newly developed advanced carbon layup that maximizes stiffness without adding unnecessary weight, ensuring race-ready durability and confidence on rough terrain.
• Featuring a wide hooked rim profile, the EXTREME C52 allows for a broader range of tire selections and ensures a secure bead lock. The hooked rims offer a secure tire fit for higher-pressure road use and aggressive cornering, reducing blowout risks and enhancing safety.

HUB

• The hub is crafted from aerospace-grade aluminum and features a newly designed shell that delivers high structural integrity while keeping weight to a minimum. Precision machining ensures tight tolerances and long-term reliability.
• The ratchet system hubs offer a fast engagement and efficient wheel for a smooth riding experience, which is beneficial for rapid acceleration in the race and riding engaging various speeds and technical cornering.
  
• Inside the hub, a wave-form spring provides smoother and more consistent power transfer. 
• The hard-anodized hub axle achieves a tolerance within 0.003mm, boosting stiffness and precision.
• The new ratchets are treated with a vacuum-plated anti-friction coating, which minimizes drag and enhances long-term durability. This high-tech finish ensures the hub runs smoother for longer, even under heavy load.
• Lightweight freehub body equipped.
• Designed with user-friendly maintenance in mind, the hubs require no specialized tools for servicing. This makes upkeep straightforward, allowing you to keep your wheelset in top condition with minimal effort. The easy-to-service design also ensures that you can perform routine maintenance and repairs quickly, minimizing downtime and keeping you on the road.
• Tool-free freehub body exchange supports multiple groupset systems for added convenience.

SPOKE & NIPPLE

• Bladed lightweight carbon spokes feature an aero-flat profile. Despite their ultralight construction, carbon fiber's high tensile strength ensures that the spokes can withstand significant stress and impact without compromising performance. 
• With stiffer and lighter carbon spokes, Extreme C52 wheelsets can reduce the spoke hole count, offering outstanding stiffness while making no compromise on the weight.
• The T-head carbon spokes anchor securely into the hub via a T-shaped interface, contributing to the wheelset’s overall stiffness and longevity.
