The definition of “road cycling” now includes gravel and off-road in addition to conventional roads. At the same time wheels are evolving to meet the needs of smaller riders. Meeting these two different requirements was the driving force behind the Zipp 303 Firecrest 650b Tubeless Disc-Brake wheelset. The smaller rim size provides the necessary space in the frame and forks for wider tires from 28 mm which provide more comfort control and better cornering. Thanks to more tire volume between the rim and the ground the overall diameter including the tire resembles a standard 700c wheel and road tire combination. Back on the road the 650b is a better fit wheel for smaller athletes riding smaller frames. For too long many smaller cyclists have trained and raced on standard 700c wheels. As a result they have lost the benefits of a properly fitted wheel such as improved handling and the elimination of overlap between the front wheel and toe. At the heart of the 303 650b Firecrest Tubeless is a versatile and durable hub set the ZR1 DB developed in Germany.
