Well I'm pretty new to cycling as a sport. I heard my university had a big cycling community, so I took the old K-mart 26" that was rotting in the shed and took it for semi-long rides(2-3miles_ around my hometown. I only used like two gears. The thing was hard to shift, I only left it on the biggest or mid chainring and always on the smallest cog. It was very flat where I lived, then at college, I found the hills. I started hitting these hills with my junky bike, broke the rear cog on my cassette. I had been seeing all the bikes around campus, one of my friends had one. It was a fixed gear, so I broke down and got one. I've been riding harder ever since. I've put alot of miles in, and I'm looking to buy a cannondale roadbike from a friend to start doing some real distance. I'm also starting to train for track racing in the summer.
Fixed gear was my gateway drug.
