Hi. New guy on the forum looking for some (any) info.
Found this at my local Yellow Bike Project and brought it home. Nice 5-speed drop bar bike. I'd post pics, but my camera isn't cooperating.
Here's what I can tell you:
Looks to be 70's vintage. Head badge reads "Cicli Dolomiti, Mexico". Welded steel frame with a reinforcing collar acting as a seat post clamp. Nice cast lugs front and back stamped "Magistroni". Crankset and alloy center-pull brakes are also marked as "Magistroni".
Unmarked alloy rims on low flange steel hubs. 27" x 1.25" Tornel tires (also made in Mexico). Hubs are cylindrical with no ridges, grooves or markings. Front is 1 1/8" diameter. Rear is 1 1/4" with a 5 speed cluster (14-22), freewheel reads "SY Freewheel - Made In Japan".
Shimano "RS" derailer. Only marking besides "Product of Japan" is stamped "HH".
