...Specialized Dita.? So i am looking to either buy a Specialized Langster Seattle or Specialized Dita. The langster is a single speed but has a flip flop wheel so it can turn into a fixed gear bike. The Dita is a geared bike. I am looking to ride the bike just around Mill Valley and for exercise but don't know which would be better. I haven't ridden a bike in a while but want to get back to it. The Langster is visually appealing but don't know if it would be the best bike for the area. Any advice and recommendations would help. Thanks!
