i just stumbled upon this Schwinn Sprint a week or so ago... with a sign on it that said "free, merry xmas". i've been looking for a first fixed project bike, and this seems like a good candidate. good drops, size seems to fit ok. and the brief time i've been able to ride it, seems to ride fine. i'm just wondering if any of you with better knowledge than me forsee any problems with converting this to fixed...

i measured it, and it seems like it's a 58cm frame.. from what i can gather anyway.. i can't find markings on it that say what it is. i'm almost 6', and it seems to ride just fine. i have no idea what year it is... tried searching the Schwinn vintage site that someone had previously mentioned, but it doesn't go through the 70's or later... no clue what year this is... serial starts with a 63. any thoughts?
