Hallo! i want to change some broken bits in my bike

1. the front derailleur.
It is high clamp or low clamp? Will this fit ok?

What is the indication 63-66? There is another one that has 66-69.

It is the only i can find that has max teeth 44-48 and is 3x9.
The crankset is 44x32x22

2. the internal axle (not the quick realease) of the front commencal hub (doesn't have fix bearings, but open) . Can you show me something that fits it? Especially from the shop above.

Thank you!
