Beyond Blacktop

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 wheel.

Features of the ZIPP 303 Firecrest Carbon Wheel

  • Zipp graphics and cosmetic identity that scream speed
  • Versatile 45mm rim profile for increased speed and better cornering, control and comfort
  • Tubeless design provides secure performance when ridden at lower tire pressures
  • ZR1 DB hubset is engineered in Germany with better seal design for improved durability and quicker response
  • Built with Sapim CX Sprint J-bend spokes
  • Center locking rotor interface. Lockring is included
  • XDR™ or SRAM/Shimano driver bodies
  • Weight: 1520g

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.

ABLC Sawtooth

Zipp’s Sawtooth dimple design consists of 12 nodes that are specifically clocked to start aerodynamic shearing at a rate of 50hz at a rider speed of 20mph. Sawtooth accomplishes this by inducing small sheet vortices that shed at a low magnitude, but at a higher natural frequency, thus decreasing the laminar bubble effect on the aerodynamically shielded side of the rim’s profile to further reduce high yaw drag and improve crosswind stability.
