Zipp 404 Firecrest Carbon Tubeless CL Disc Brake Front Wheel ZPWH8620000

Zipp 404 Firecrest Carbon Tubeless CL Disc Brake Front Wheel The 404 Firecrest Carbon Tubeless CL Disc Brake Front Wheel has been designed via Zipp’s holistic “Total System Efficiency” concept that balances aerodynamics, weight, rolling resistance and comfort to create a performance ideal for road races or timed solo efforts. The full carbon rim utilises a hookless tyre interface that naturally reduces its weight without sacrificing any stiffness or strength. This hookless design has a 23mm wide internal measurement to better support the sidewalls of tubeless-ready tyres, helping them to grant reduced rolling resistance while using comfort-inducing lower inflation pressures. The wider internal rim dimension helps to smooth the tyre-to-rim interface, and this works in conjunction with the refined 58mm deep rim profile to scythe through the air and promote extra stability in crosswinds. A dimpled surface completes the rim, further lowering drag. A Zipp ZR1 DB hub spins smoothly and is durable, and is linked to the rim via Sapim spokes arranged in an efficient and durable two-cross lacing pattern. Includes 12mm hub end caps Center Lock lock rings Highlights The versatile, good-value 404 Firecrest is an exceptional pick for road races or efforts against the clock Conceived via Zipp’s “Total System Efficiency” (TSE) design concept that equally factors aerodynamics, weight, rolling resistance and vibration losses (comfort) A special tool that measures aerodynamic drag, rolling resistance, wind speed and wind yaw angle while on the road, was key in the development of these wheels  The TSE holistic design approach equals more speed in real-world riding conditions rather than just wind tunnels The rims use a high grade of carbon fibre to lower weight, increase strength and improve lateral stiffness The hookless internal rim design is for tubeless-ready tyres only, promotes a more aerodynamic tyre to rim interface and lowers weight via more even resin distribution A 23mm internal rim width works optimally with wider tubeless-ready tyres, lowering rolling resistance and improving comfort Optimised tyre bed for easy tyre installation The 58mm deep, refined rim shape optimises aerodynamic efficiency and crosswind stability An intricate rim surface ABLC dimple pattern further lowers drag The ZR1 DB hub has a better seal design for improved durability 24 Sapim spokes are laced with an efficient and durable two-cross lacing pattern Lifetime Warranty
