The fore-aft adjustability of the saddle rail clamp makes it look very fragile, and you have confirmed my concern. If the frame takes a regular round seat post I would have bought this bike, because Bianchi celeste.
The piece that broke looks like half of a miniature vice with a hole through the middle and is concave. It’s probably an inch long. When I first got the bike I was constantly moving the seat fore and aft, adjusting the tilt and evidently all the tightening and retightening did a number. Maybe over tightened?
