Hey guys this is my first post here, I just bought my first "real" bike yesterday. I got an Opus Belcanto single speed off craigslist. The previous owner changed the handle bar, crank set, wheels and seat post. its got an aluminum frame with a carbon fiber fork and carbon fiber felt seat post. I am very much a noob with bikes but Im researching and trying to learn more. Im not a fan of the handle bar so I will be changing that right away. Overall I like the bike so far.
