I started mountain biking on a 24-speed rigid Rockhopper in November '03, and in May '04 I bought myself a big squishy 27-speed trailbike, so I gave my Rockhopper the SS treatment and used it mostly for commuting. I loved it because it was so simple, I never had indexing problems like with my FS bike, it was light and it looked cool. Then, when school started back up, I had to head across the country without my bikes, which made me so sad that I decided to purchase a new one. I didn't want another MTB, but I wanted to be able to ride with the school's Cycling Club, and use it as a commuter, so I decided that a fixed gear road bike would be cost-effective and fast enough for club rides. I ordered an IRO Jamie Roy, and rode 30 miles on it the day after receiving it with some guys from the club. I was instantly hooked. Now I try to convince my friends to ride fixed or at least singlespeeds. I feel weird using two brake levers, even weirder coasting, and shifting gears is seriously disorienting. I think that I was actually destined to ride fixed because when I'm climbing seated on a geared bike, I feel like I'm spinning too much and moving too slow, so I quickly get impatient, shift to a hard hard gear and stand and hammer my way up. I guess it just fits my riding style.
