I want a road bike but don't want to have to deal with adjusting the shifters because the derailleur setup confuses the hell out of me.
I bought a fixed gear because of the reason stated above and I absolutely love it.
When I am on my track bike on the road it is always a race, always. Doesn't matter what you are on, BSO or $10k full carbon road bike, it is a race.
I enjoy passing cars on the road in a 25mph zone on a fixed gear bike while I am commuting to work.
I had a black Aerospoke front wheel and sold it, and deep down, I wish that I had kept it.
I bought a SRAM S80 front wheel for no reason other than I like how it looks. Commuting to work on a windy day with it on my bike is more than a challenge.
