i was given a bmx bike ive been told its very old, there was a horrible paint job on it and it looked really bad so i sanded it down today to the metal to primer it and i found company markings, on the left rear tire mounting plate it says CHAIN BIKE CORP, the right one has the following stamped in it 133-12 wish i belive is the model number but i was wondering if anyone could help me figure out what kind of bike it was or bring up any kind of information on it, pictures, year, frame matterial, specifications, ect. ect. thank you for your help.

Hello, The "Chain Bike Corp." was actually ROSS bicycles of Allentown, Penn. They went bankrupt in 1989 For the last 3 or 4 of that time they couldnt compete with cheap overseas labor and tried to lease a few factories in Taiwan to survive but ended up going under because of poor sales along with with several harsh EPA violations!! A company called Rand Cycle bought the ROSS name out of bankruptcy and hired Sherwood B.Ross as a consultant for 5 years as part of the name deal but "Rand" never sunk money into marketing the ROSS name and although they still own it they havent nor see anytime in the future where they would.... Sooooooo, to make a long story short... Your "so called" very old BMX bike might well be an 80's model but ROSS bikes werent exactly known for anything special.. Also, being that it says Chain Bike Corp. It actually on of the Taiwan made really junky models.. They used Chain Bike Corp. as a alias type name overseas.. Well, glad i could help but sorry it wasnt good news.... Take Care
