Hello. I was given an incomplete bicycle from a neighbor and have been trying to research it for quite some time. I am interested in putting money into it to get it rideable. I cannot find any distinguishable brand markings for the frame, the only thing I can find are a stamped serial number on the bottom that reads "R149", with the digits being stamped vertically. There are also decals placed on the downtube spelling "EILLEEN", which I am assuming was the last owner??? The handlebars are 3ttt and there are some BCA lugs on it too, along with Dia-compe brakes. For all you experts out there, please take a look at the pictures and let me know your thoughts on whether this bike is worth putting time into. Thanks.
