Engineered for the demands of modern road cycling, this wheelset is a master of versatility, providing an uncompromising advantage on every terrain. Whether you´re conquering steep climbs, sprinting for the finish line, or navigating challenging pavé, the 303 Firecrest is designed to make you faster, more efficient, and more confident in the saddle.At the heart of the 303 Firecrest is Zipp´s groundbreaking Total System Efficiency (TSE™) design approach. This philosophy focuses on overcoming the four main barriers to speed: wind resistance, gravity, rolling resistance, and vibration losses. The result is a wheel that doesn´t just slice through the wind but also enhances comfort and grip, allowing you to transfer more power directly to the road. Its 40mm rim profile strikes the perfect balance between superior aerodynamics and stable handling in windy conditions, giving you a predictable and secure ride feel.The wider, hookless rim profile is a game-changer for performance. It creates a seamless transition between the rim and tire, significantly reducing aerodynamic drag. More importantly, it allows you to run wider tires at lower pressures. This not only smooths out road chatter and reduces rider fatigue but also lowers rolling resistance and dramatically increases cornering grip. Paired with a responsive and durable ZR1 DB hub, every watt of your effort is translated into instant forward momentum. For cyclists who demand powerful, all-weather stopping power, the disc brake compatibility ensures consistent and reliable braking performance on every descent.This wheel is the ultimate upgrade for the dedicated road cyclist looking to gain a competitive edge and enjoy a superior ride quality on every journey.Key Attributes: 28´´- 700, Carbon, Clincher, Disc Brake, High profile > 40 mm, Rear, Road Cycling---Specifications:- Speed: 11/12- Size (Wheels): 700c- Rim construction: Carbon – Hookless- Tire compatibility: Tubeless Clincher- Brake compatibility: Disc (Center Lock)- Driver body type: SRAM/Shimano Road- Rim finish: UD fiber, ImPress graphics- Rim profile: Symmetrical, 40mm Depth- Weight: 739g
