Zipp’s 303 line has long been a hit amongst cyclists for a balance of weight and aerodynamics, along with storied wins such as Fabian Cancellara’s back to back 2010 Tour of Flanders and Paris Roubaix victories.
The 303 has since gone on to cement itself to be a versatile all-around wheelset, along with a few updates. The latest addition to the lineup, however, is the arrival of the most affordable 303 to date, the $1,300 303 S.
Zipp’s other affordable full carbon wheelset, the 302, has been around for a few years, and in a way, the 303 S is more of a continuation of the 302’s affordability, plus more tech one would expect from a 303.
The 303 S retains the 45mm rim height but has a new wider disc and tubeless tire only rim measuring at 27mm externally and 23mm internally. It is also hookless which Zipp claims reduces drag and is optimized to be fastest with 28mm tires, along with a max tire width of 50mm for gravel. The new rim profile allows users to run lower air pressure where Zipp actually recommends users not to inflate above 73 psi. Cosmetically, the 303 S sports a new redesigned permanent graphic under its matte clear coat, a subdued departure from its classic removable Zipp decals.
The symmetrical 303 S rim is then laced two cross with 24 Sapim CX-Sprint j-bend spokes front and rear with external brass nipples. The 303 S is thru-axle only (12 x 100 front, 12 x 142 rear) with the same durable Centerlock-only 76/176D hubsets with either SRAM XDR, or Shimano HG free hub bodies, with Campagnolo driver available as a stand-alone aftermarket option. At 1,540 grams, the 303 S is 155 grams lighter than the 302.
The 303 S is available today.
