I am putting together a Nishiki Century (tange 5 I think) to sell next weekend. I pilfered a few parts off of it, all replaceable. Should I build it back up as a 10spd (original) w/ stem shifters or build it as a coaster brake 27" wheeled city bike? There is a bike boom woman's bike that I can have for free that has 27" coaster brake wheels and upright bars. The original dropbars were bent badly and have been scrapped so the upright bars are going on regardless. What do you guys think would be the best way to assemble the bike to get maximum buying audience? I think people from NYC or Philly would be my primary buying audience either way....
