If you had to choose just one wheel, the 404 Firecrest should be your choice. With the depth & shape proven in all conditions, it’s the all-around performer & the standard by which all other wheels are measured. Its 58mm rim depth is a classic all-around performer that has carried athletes to victory in every kind of event & situation – every triathlon distance, breakaways, field sprints & hilly finishes. The 404 Firecrest Carbon Clincher is where the Firecrest Revolution began as the first deep-profile carbon clincher design to offer the superior aerodynamics, ride quality, strength & handling of a wider rim body. Yet the 404 Firecrest Carbon Clincher weighs 1, 690 grams per set, providing best-in-class performance at a light weight. At the center of the 404 Firecrest is Zipp’s 77/177 hubset with best-in-class durability & enhanced bearing protection with no pre-load adjustment needed. The result is enhanced stiffness, durability, simplicity & versatility.
