Zipp 404 S Carbon Wheelset The Zipp 404 S Carbon Wheelset is built for riders who want a serious aerodynamic upgrade for fast road riding, racing and high-speed training. Combining a deep 50mm rim profile with a modern wide internal rim design, it delivers the speed benefits expected from a performance carbon wheel while also improving comfort, grip and control with wider tubeless tyres run at lower pressures. The result is a wheelset that feels efficient on the flat, composed through sweeping corners and more forgiving across broken road surfaces, making it a strong choice for riders chasing all-round road speed without stepping into top-tier race pricing.
