Front derailleur

At last I got bottom bracket for sports bike.
then I could attach front derailleur.

 Bigger chain wheels has 52T. Smaller one has 39T. The one with 42T touches the frame, so it was changed to 39T's.

 I changed the chain new one. I bought 2nd hand chain wheels. I had to bend then to adjust.

 The spring of the front derailleur is too hard.
