Pro bike: Jeremiah Bishop's Cannondale Flash Carbon 29er

Lightweight bikes are nothing new at the top ranks of the sport but Jeremiah Bishop's (Cannondale Factory Team) Cannondale Flash Carbon 29er surprised even us, weighing in at an astounding 8.23kg (18.14lb) – lighter than some Paris-Roubaix machines we've profiled in the past and just the thing for the US cross-country national championship's climbing-intensive course in Sun Valley, Idaho.
