Zipp 808 Firecrest Tubeless Rear Wheel - 700 12 x 142mm Center-Lock SRAM 10/11-Speed Tubeless BLK B1

Zipp 808 Firecrest Tubeless Rear Wheel - 700 12 x 142mm Center-Lock SRAM 10/11-Speed Tubeless Black B1. The 808 Firecrest Tubeless Disc-wheels are all about science to achieve speed. That’s the perfect approach for Zipp’s stiff deep-rim choice for criteriums road racing or any kind of hammer-fest. At 80mm deep its rim is designed to make you faster in every way. Zipp’s Total System Efficiency design approach or TSE infuses the 808 Firecrest with new features including a huge drop in weight from its previous iteration well more than 280 grams. Also the wheel is designed with a hookless and tubeless rim profile and 23mm internal width. That’s ideal for running wider tires at lower pressure for reduced rolling resistance and greater cornering grip.

TSE attacks the four primary barriers to speed: Wind Resistance Gravity Rolling Resistance and Vibration Losses

Full Carbon Firecrest rim shape provides high aero efficiency and crosswind stability

ABLC Technology uses a complex dimpling pattern to improve aero efficiency

Optimized for tubeless tires with the option to run Tubeless or tubeless ready tires with tubes
