^ Concur with Chombi1 on some points but not all. Yes, can compare the KL aerodynamica (funny name because I see nothing aero about it) derailleur to Campy N/S Record but the Galli can be fully dismantled and bench serviceable at the parallelogram.

Story goes Galli was first in producing calipers in ally. Whatever. Anyways, they did job lots for some parts for Campagnolo. Later years as all were growing for market share, the groupo ensembles was becoming difficult to compete with Campagnolo, considered by some as the creator of group sets. So Galli ganged up with brand labels French and Italian.

The 80's era KL vs Criterium brakes are notable different. The Criterium are lighter in weight and even had offered with ti fitted fasteners. Though their top line KL were a few grams heavier but really are the better brakes, shaped different and beefed up arms especially the area where the shoes attach. The slots too are for larger diameter bike shank / shoe stud.

Headsets are nice stuff. They did have the tapered needle caged bearing type from Stonglight.
However they also had their own Timken like tapered roller bearing. Top and bottom. They're rare. If you find them, make sure its all complete with the lower race and seal. Robust headset. Takes a little more patience in setting pre-load and tolerance.

Like the above headset, they also offered a Timken like tapered roller bearing bottom bracket and ti spindle. Doubt anyone has worn them out. This stuff is like automotive or tractor grade applications.

Some of their upper model cranks are beautiful and lightweight. They finished both sides of the arms, fluted etc.. Most if not all can interchange with same era Campagnolo.
