Here's the evolution of the 303 in the past three years. You can see that the 2010 shape was actually pretty close to Firecrest, which is why Zipp waited until they had sped up their other rims before returning to the 303.
Zipp has just announced the 303 Firecrest, available October 3rd, and the new Beyond Black colorway across all its spoked wheels that brings a really stealthy look to Zipp's already gorgeous carbon hoops.
True to its name, this race by the ocean had an expo right on the beach. We're here covering the race, so be sure to check back for more as the weekend rolls on.
