Just for share, I'm super happy regarding it.
It is a gift from a friend, she traveled a lot with this bike. The bike has a long story too, started from California and now on south Italy.
it's a dahon equipped with altus 7v 11/38 (52).
basically I'm going to swap a few worn parts (chainring, derailleur's pulley and chain).
plus a deep clean and a bit of polishing.
Interesting the fact that the frame is made from cromoly
