I have recently become reinterested in bicycling. 30+ years ago I was major into it and once rode across the US (took 3 months to do it, on sew-ups). I still have the bike I rode...I was thinking I need to get a new bike but I was wondering what I've got. It is a Rex Criterium frame made with 631 tubing, chrome lugs, leather saddle, Campy stuff and hubs. Would it be worth recomponenting the frame? Call it vintage and get a Trek?
