| Zipp 808 wheels are an amazing combination of | | | | 808 Tubular Specs |
| research, technology and racing experience. Zipp | | | | Total Weight - 1499gwith Powertap - 1743g |
| redesigned the 808 in 2009 to an 81mm depth. A new | | | | Front Wheel |
| 88/188 hub is stiffer, more reliable and faster to | | | | Weight - 691g |
| engage than the old design. Tire-to-rim interface and | | | | Rim Used- 420Hub Used - 88Spoke Count - 16 |
| lateral stiffness has also been improved. The slightly | | | | Spoke Pattern - Radial |
| heavier hubs improve the stiffness of the hub and rim | | | | Spoke Length - 222mm |
| while the decreased spoke count of 6 spokes | | | | Track Adaptable - Yes |
| compensate for the heavier hub. Zipp claims the 808 is | | | | Dimpled Surface - Yes |
| nine seconds faster over 40k than the previous 808. | | | | Rear Wheel |
| The 808 can help them conserve energy while sitting | | | | Weight - 808g |
| in the field and achieve a greater top speed at the end | | | | Rim Used - 420Hub Used - 188Spoke Count 20 |
| of the race. These benefits can be had with the Zipp | | | | Spoke Length Non-Drive - 226mm |
| 808 without the loss of rapid acceleration and precise | | | | Spoke Pattern Non-Drive - Cross |
| handling. Roues Artisinales tested a multitude of racing | | | | Spoke Pattern Drive - Radial |
| wheels and learned that the 808's absorb 16.7 watts | | | | Spoke Length Drive - 210mm |
| of energy at 50kph. By comparison, the Mavic Ksyrium | | | | Track Adaptable - No |
| Equipe from 2007 absorbs 30w. That's 44% less | | | | Dimpled Surface - Yes |
| energy! I wonder what speed would have been | | | | I tried them out at the 2010 Ironman St. George, Utah. I |
