The Kashimax Aero saddle has a unique history, starting out as a BMX seat in the 80's with certification for the strictly regulated Japanese track racing. The super light, 44mm wide saddle was re-released back in the winter of 2008 due to demand from the track bike crowd and now, receives a Chari & Co. NYC makeover. Cop one now in black or red for $164 from the Chari & Co. online store. Check out a video of a recent visit to the Kashimax factory for some more insight on the saddle's history below:
