Details: When the professional peloton takes its spring campaign tothe grueling cobbles of Roubaix and Flanders, you can count on the fact thatZipp sponsored teams will be on its 303, after all, the wheelset has therenowned distinction of being the first carbon wheelset to win those venerableclassics. If you're building up a new ride or your trusty steed is in need ofsome new wheels, have a look at the Zipp 303 Firecrest Carbon Clincher RoadWheel knowing that it will add speed, drop weight, and add bombproofversatility on any race day or training ride. Zipp gives the 303 Firecrest a 45mm rim depth providing anaerodynamic advantage while maintaining its positive handling traits inblustery conditions for a smooth, stress-free experience that will have riderson lesser wheels testing their nerves. A wide, 26. 4mm external width gives thetire a secure and solid stance helping to decrease rolling resistance andincrease stability by reducing the "lightbulb" effect found whilemounting tires to narrower rims. You'll descend like a demon with the new-foundconfidence that these wheels provide and get inspired to contest every sprintand dive into corners like you're on rails to get the jump on the competitionwhile still providing a comfortable ride along the way. Zipp built these wheels to handle pancake flat, albeit bumpyroads, as well as beyond category climbs, but never lost sight of giving thesewheels an aerodynamic advantage. Zipp's signature Aerodynamic Boundary LayerControl (ABLC) dimpling features strategically placed and sized dimples acrossthe rim surface to smooth airflow, allowing the wheel to slice deftly throughthe air. ABLC boasts aerodynamic advantages in real-world wind angles, givingit an advantage over many wheels that experience minimum drag numbers at windangles that rarely occur outside of a wind tunnel. In a nutshell, these wheelswill handle the windy conditions you'll run into out on the road better thanmost of the competition. At the ...
