Experience the pinnacle of road, triathlon, and time trial performance with this ultimate aero-weapon. ZIPP 858 NSW CL Disc Tubeless Road Rear WheelExperience the pinnacle of aerodynamic innovation with the ZIPP 858 NSW CL Disc Tubeless rear wheel, the ultimate aero-weapon designed for serious road cyclists, triathletes, and time trial specialists seeking uncompromising speed and control. Engineered to be the fastest deep-profile wheel ZIPP has ever made, the 858 NSW delivers a revolutionary performance advantage that you can feel on every ride, from flat-out sprints to challenging, windy courses.The defining feature of the 858 NSW is its groundbreaking, biomimetic Sawtooth™ profile. This unique, undulating 85mm deep rim design takes inspiration from nature to simultaneously reduce both aerodynamic drag and side force. The result is a wheel that not only slashes through the wind with incredible efficiency but also provides a level of crosswind stability and predictable handling that is unprecedented for a wheel of this depth. This allows you to stay in your aero tuck with confidence, holding your line and conserving energy even when conditions are less than perfect.At the heart of the 858 NSW is the advanced Cognition V2 hub, engineered with Axial Clutch V2™ technology. This system significantly reduces mechanical drag when you´re coasting by disengaging the ratchet mechanism, allowing the wheel to spin more freely. This translates into tangible watt savings, preserving your energy for when you need it most—whether it´s accelerating out of a corner or launching a final attack. The powerful and reliable Centerlock disc brake interface ensures superb stopping power and modulation in all weather conditions.Built around Zipp´s Total System Efficiency™ (TSE™) design philosophy, this wheel is optimized for real-world performance. The hookless carbon rim profile and a wide 23mm internal width are engineered for seamless integration with modern, wider tubeless tires. This setup allows you to run lower tire pressures, which creates a broader contact patch for reduced rolling resistance, enhanced cornering grip, and a significantly smoother ride that mitigates road buzz and vibrational losses, keeping you fresher for longer. The ImPress™ direct-print graphics not only provide a sleek, stealthy aesthetic but also save weight by allowing the UD carbon fiber to shine through.This is more than just a wheel, it´s a comprehensive speed system designed to make you faster.Key Characteristics:* 28´´- 700* Carbon* Disc Brake* High profile > 40 mm* Rear* Road Cycling* Tubeless---858 Nsw Cl Disc Tubeless Road Rear WheelSpecifications:* Item Type: Wheel* Item Name: 858 Nsw* Size: 700c* Front/Rear: Rear* Use: Road / Triathlon / TT* Brake Type: Disc Brake* Axle And Old: 12x142 mm Thru Axle* Boost Compatible: No* Body: SRAM/Shimano* Tire Type: Tubeless Tires Only* Rim: Carbon Hookless Clinchers* Rim Width: Inside: 23 mm* Rim Profile: 85 mm* Rim Color: UD Fiber, Impress Technology* Mounting Type Rotor: Centerlock* Hub: Cognition 2* Corresponding Wheel: 00 1918 697 000* Other: Surface: ABLC HexFin, Max Pressure: 73 psi. tradeinn Bikeinn
