We're taking our first look at Zipp's new Firecrest line. We have both the 404 clinchers (pictured here), and the 808 clinchers mounted up and being ridden for review. But we couldn't rob you of some of the details before we get to our in-depth review of the wheels. So before laying down rim tape and pumping up the tires, we thought we'd take a look at the construction details, and examine everything we could before finally putting in the miles.
The sidewall, which may appear to be fairly flat, actually has some subtle curves which Zipp says helps with the aerodynamics.
