If you compare the picture with the
Ridea FD mounting specially made for the Birdy, the Litepro very different and the FD is mounted at a very different place wrt. the collar of the adapter.
For the chainrings bolts, the one for standardized BCD130, BCD110... chainrings are standard and exists in lengths for single, double and triple chainrings, your mechanic can surely provide you the good ones.
These guys used Litepro FD adaptor for Claris R2000 braze-on derailleur and 50/34 chainrings from Ridea. You can list through the pictures with all details of the installation.
Assuming adaptor design hasn’t changed I believe it should work too. Is 40mm adaptor what I need? If Ridea adaptor will not be shipped I’ll have no choice but to go with Litepro.
