Crank2 is a full service bike shop. We specialize in tandem bicycles, but are also the #1 dealer for the Volagi Lisco & Viaje road bikes. Crank2 is located in Pleasanton, California just minutes from the I-580/I-680 corridor. We are a destination store that attracts people from all around the country, but primarily serve the greater San Francisco Bay Area. We have a thriving online internet buisness as well.
