Interbike 2011: FSA Metropolis RL Policar September 19, 2011 3 bike train, Commute, Commuter Bikes, Interbike 2011 FSA Metropolis, patterson planetary cranks Did you know that Full Speed Ahead (FSA) does commuter stuff? Well here’s a great start, this is the Metropolis Patterson Transmission. It sorta reminds me of the Truvativ HammerSchmidt cranks. They have a whole line of Metropolis components available for the urban rider. This bike is a perfect example on how its equipped with the groupo.
