Zipp 808 Firecrest Tubular rim shape has improved in almost every measure. Its 27mm-wide profile is 15 seconds faster than before over 40km, and now equals or exceeds the performance of any 90mm-deep rim on the market as well as many discs. At high wind angles, the 808 aero advantages is even greater, New Firecrest design also makes the 808 remarkably stable. Essentially, the 808 provides the speed of a much deeper rim with the handling of a much shallower one. With its wider profile, the latest 808 Tubular also shows improved lateral stiffness for efficient power transfer and crisp acceleration, yet offers greater comfort and impact resistance than its predecessor.

Zipp 404 Firecrest Tubular with the advanced Firecrest aero rim shape, By controlling airflow around the back half of the wheel, Firecrest makes the latest version of the 404 9 seconds faster than its predecessor over 40km at a moderate 10-degree wind angle. At higher wind angles, the improvements are even more dramatic in terms of both speed and stability. That is because Firecrest moves the center of pressure closer to the steering axis, so crosswinds exert lower side force on the wheel.
