I wanted to start off by saying what a great forum you all have here. The amount of good information on current and past bikes is unsurpassed on the internet. I read most of the threads on serial numbers and such but not much help. I did have a question about my Masi. I purchased it brand new in '96 - it has M57 and 9054 stamped on the bottom bracket around the shell not on the flat part (if that makes any sense). My question is: what can you gather from the numbers? The seat stays have MASI stamped on them, the brake bridge is not round and has MASI stamped on it twice, flat crown fork, it's red, there is a big M on the bottom bracket. Thanks in advance for your information.
