Everyone claims to have the fastest bike on the market, but Kestrel have actually produced it. They took the 4000 frameset and its components to the A2 Wind Tunnel and tested it from every angle, with multiple parts, in order to design a superbike that performs just as well in the wind tunnel as it does on the lava fields of Hawaii. Not only is the 4000 outrageously fast, it's one of the best fitting, most comfortable bikes on the market because they know that after 112 miles on the bike... your body's still got 26.2 to go.
