Green Basikal didn't organise the pictures into an album, hence you can read up the comments in each photo to piece together the puzzle.

Birdy conversion from 1x to 2x Chainrings. Objective is to have lower gear ratios for ease in climbing.
Contrary to many commonly seen Birdy conversions where riders just want to ride fast, faster and fastest, with increasing bigger chainrings, we actually swap the original 52T to 50/34T chainrings.
The original 52T w/11-32T (9s) Birdy has a range of 27.9 to 81.1".
With the swap to 50/34T double chainrings, the new improved gear ratios became 18.2 to 78".
Now he can C L I M B.
