Without Limits: the 303 Firecrest® Tubular wheel by Zipp

Zipp's new 303 Firecrest Tubular Rim and Disc-brake wheelsets offer fresh innovations for performance minded cyclists. Retaining their versatile 45 mm rim depth, 303 Firecrest Tubular rims now feature construction upgrades that deliver improved impact resistance. The new wheels also borrow key features from the halo-level NSW lineup. Both the rim and disc brake variants gain
the ABLC™ SawTooth™ dimple design for greater AeroBalance™, while
the rim brake variant now includes the Showstopper™ brake track for the best braking control and shortest stopping distances in both wet and dry conditions. These innovations enhance the
wheelset that's been podium-proven in two of pro cycling's harshest proving grounds, the Spring
Classics and cyclocross-and then take that performance to the next level.

Note: The rear 303 Firecrest may present some fitment issues for a small number of older road and triathlon frames, including the 2012 Specialized Tarmac SL4 and Specialized S-Works McLaren Venge. Clearance between the chainstay and the rim may not be adequate to avoid contact between each other when ridden under load.


Zipp's industry leading silicon carbide ShowstopperT brake track continues to evolve and improve, providing unmatched stopping power and modulation regardless of weather conditions or the length of the descent.

This patented rim shape achieves something conventional aero wheels cannot; it simultaneously reduces both aerodynamic drag and side force for the ultimate in AeroBalance™. SawTooth™ accomplishes this with ABLC dimples for improved airflow. The result is both aero-drag reduction and reduced side force at all wind yaw angles. This is important because higher wind yaw angles are where bike handling is most affected by the wind.
