Product Overview
The 404 Series is designed to excel in triathlons, road races, and time trials. This lightweight wheel/wheel set might be the perfect choice for cyclists looking for an aerodynamic advantage on the road and want to use the same wheel/wheel set in triathlons and time trials. From victories at the Ironman World Championships to victories in the Tour de France, the Zipp 404 series has proved itself over and over again across the racing spectrum. Clydesdale version features increased rim stiffness and a 208 hub to deliver greater torsional stiffness for heavier riders.

Employment
- Triathlons / Time Trials: 58mm rims with dimple technology and bladed spokes improve aerodynamics to slice through the wind with ease. At only 728g (tubular front) the 404 Clydesdale saves you energy at the most energy inefficient moments – accelerating and climbing (this point is especially critical for women and lighter men as changing the momentum of a heavier wheel is increasingly harder as the wheel’s weight is a higher percentage of the total bike/rider weight). Still not convinced? Women’s 1st, 2nd, and 3rd place finishers in the 2006 World Ironman Championships rode 404 wheel set!
- Road Racing: Aerodynamic advantage, low weight, and vertical stiffness makes the 404 series and excellent choice for variable terrain road racing – fast on the flats, quick up the hills, and precise around the corners. Break away from the peleton with confidence!

New for '08:   
-Dimpled 108mm carbon rims for incredible aerodynamics.
-Carbon Bridge: Kevlar thread in a co-axial helix stitch improve rim strength by distributing impact force. According to Zipp, the Carbon Bridge results in "28% more impact resistance than any other rim made at this weight".
