Hey everyone I am thinking of getting into the world of road cycling, but I have a few questions first. I am a 16 years old and I love riding bikes and I am looking to lose some weight while having fun, would this be the sport for me? My second question is are the road bikes at Wal-Mart or K-Mart as good as the ones at my LBS? Because I have a pretty old road bike as of right now, probaly pretty close to 32 years old. It has been up in the attic a while but would that be ok to ride for the time being until I see if I really do like this sport? It still rides fine and I did a tune up on it already. Or should I buy a new one?

Thanks for reading,
Adampff
