Sorry for the late reply everyone. Been busy at work. I returned the bike. I learned that it was originally a 7 speed and the seller tried to cheat on me. I managed to let him tell the truth since a 5 speed is really suspicious on a 130mm. I bought it from a custom bike maker so I can already guess what he did. I guess I can just focus on centurion for now since it's the downtube shifter I'm really after.
