Zipp makes the impossible possible with their Firecrest 303s—they're equally at home on the flats as they are in the mountains. The 45mm-deep rims slice through the wind with more efficiency than many deep-section wheels thanks to their 28.5mm-wide dimpled rims. By creating a seamless junction between rim and tire, the increased width results in less drag. The 303s climb with the best and re-accelerate out of corners like rockets since they barely register on the scales, which makes them a must-have on undulating terrain. The extra wide rim also allows you to run wider tires at a lower pressure with less fear of pinch flatting, which boosts ride quality and comfort and reduces rolling resistance. Zipp’s stiff hubs and Sapim CX-Ray spokes provide the finishing touches.
