2023 ZIPP 303 FIRECREST 650B TUBELESS DISC-BRAKE
The definition of “road cycling” now includes gravel and dirt as well as pavement. At the same time, bikes are evolving to meet the fit requirements of smaller riders. Meeting these two distinct needs was the driving force behind the Zipp 303 Firecrest 650b Tubeless Disc-brake wheelset. The smaller rim size provides room within frames and forks for larger tires, 28mm or wider, that deliver increased comfort, compliance, and cornering performance. With more tire between the rim and the ground, the overall wheel diameter including the tire is similar to a standard 700c wheel and road tire combination.Back on the pavement, the 650b is a better fitting wheel for smaller athletes riding compatible frames. For too long, many smaller cyclists have trained and raced on standard 700c wheels, losing out on the advantages of a proper fitting wheel such as improved handling and the elimination of front wheel-toe overlap. At the center of the 303 650b Firecrest Tubeless is a versatile and durable hubset, the German-engineered ZR1 DB.

Technology
ABLC (Aerodynamic Boundary Layer Control)
Advanced Boundary Layer Control (ABLC) refers to the patented and instantly recognizable dimpled pattern found on all of our carbon rims. ABLC smoothes airflow across the rim's surface and is tailored to every model from the 202 to the Super-9 Disc. The third-generation of ABLC has up to four times more dimples than before.
AeroBalance
Zipp’s sole mission is to help you go faster. That's why our wheels are race-ready before they're camera-ready. For years, Zipp has used a combination of testing methods – wind tunnel, CFD computer simulations, pro athlete evaluations, on-road testing, and the RollingRoad ride simulator – to refine aero performance to new levels of excellence. Over the decades of innovation, our engineers have learned to look beyond just focusing on simply reducing aero drag. Instead, the goal now is to reduce aero drag while also minimizing the effects of crosswinds on handling. This optimizing of aero efficiency and crosswind stability became known internally at Zipp as AeroBalance. The approach began with Firecrest technology and has been advanced with the introduction of the NSW lineup, especially with the Sawtooth technology found in the 454 and 858 NSW. Sawtooth accomplishes this with a series of patented fin-shaped Hyperfoil nodes along the inner diameter of the rim that work together with our new HexFin ABLC dimples for improved airflow.
