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.

Key Highlights Are
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 with 66 points of engagement
Built with Sapim CX Sprint J-bend spokes
Centre locking rotor interface. Lockring is included
Ships with 12mm front and rear end caps
XDR™ or SRAM/Shimano driver bodies
Campagnolo driver body sold separately
