Hi! Bought a centurion super lemans 12 speed road bike on Craigslist as my daily rider to my job ten minutes (by car) away. Not sure year or anything and just got new tires and tubes.... I'll get a tune up in a couple weeks. Anything I should be on the look out for? Is this bike worth revving up to become a "proper" road bike? It stared as a way of avoiding crazies on the metro, but I've lost two pounds already so this will definitely be a part of my weight loss!
