Franklin moved to Santa Clara County from New York with his 2003 Cannondale Jekyll. It's a full suspension bike with 700 road slicks, disc brakes, and the "Lefty" suspension fork.
The Jekyll is a reasonably light and fast bike for a full-suspension frame. Franklin chose this bike with road wheels to stay fast on bad roads. According to a survey by The Road Information Project (TRIP), San Jose has the worst roads in the US. This is probably for freeways in San Jose -- the surface streets are okay; I think San Francisco's streets are much bumpier than San Jose's.
