Zipp’s 808 Firecrest Tubeless rim-brake wheels makes you faster with an 82mm rim depth that’s fast, stable in crosswinds, and now tubeless ready. That means you get all the aero benefits with having the ability to run lower tire pressure for increased cornering grip and compliance and reduced rolling resistance, without the risk of pinch flats. This wheelset is infused with technologies developed in our Indianapolis advanced development lab. Zipp’s ABLC Sawtooth Technology uses a complex dimpling pattern to improve aero efficiency. Zipp’s ShowStopper textured braking surface delivers unrivaled rim braking performance in wet or dry conditions. At the center of the 808 Firecrest Tubeless rim-brake is a versatile and durable new hubset, the German-engineered ZR1. Zipp’s new wheel cosmetics make this wheelset a perfect pairing of speed and style. ShowstopperShowstopper technology uses a molded silicone carbide (SiC) surface brake ring for maximum wet braking performance. The result is a braking performance that is equal to that of an aluminium rim, even in torrential rain. Showstopper technology offers greater wet braking power than any other carbon wheel.
