650B Gravel carbon disc wheel

Zipp 303 Firecrest 650B Disc Wheels

The definition of "road bike" now includes gravel and dirt as well as tarmac. At the same time, bikes are rapidly evolving to meet the demands of smaller riders. The answer to these two distinct needs was the driving force behind the Zipp 303 Firecrest 650b Tubeless disc brake wheelset . The smaller rim size provides more room in the frame and fork to accommodate larger tires, 28mm or larger, which provide increased comfort, control and cornering performance. With more tire surface between the rim and the ground, the overall diameter of the wheel, including tire, is similar to a standard 700c road wheel/tire combination. Back on the tarmac, the 650b are wheels better suited to smaller riders who have compatible frames. For too long, many short riders have trained and raced on bikes fitted with standard 700c wheels, losing the benefits of a wheel suited to their size, such as better handling and the elimination of wheel overlap. front / foot. At the heart of the Zipp 303 650b Firecrest Tubeless is a new versatile and durable hub, the German designed ZR1 DB.

Technology

ABLC™ (Aerodynamic Boundary Layer Control)

Advanced Boundary Layer Control (ABLC) refers to the highly recognizable patented pattern found on all our carbon rims. The ABLC, which attenuates the airflow on the surface of the rim, is adapted to each model, from the 202 to the Super-9. The third generation of ABLC offers four times more footprints than before.

AeroBalance™

AeroBalance™ simultaneously reduces both aerodynamic drag and side force
