I was checking on the cranks and they came with Sugino or Kenetix. Hve you thought of a lighter saddle, lighter quick release pedals or small quick release fenders to save weight? I have the Speed Uno and I am deciding on the Sram2 speed ( I have the non coaster version but will not work on mine) or the 5 speed.
