From an aerodynamic perspective the biggest aero gains come from the front wheel set-up as it is the leading edge breaking the clean air. The rear wheel runs in the "dirty" air so aerodynamics gains will be smaller.

As stated in the other answer, the driving force behind these setups used to budget. The rear wheel is fixed gear, which limits the budget selection to old track wheels, converted freewheel wheels and self-built. Two first are high spoke count because that was all that existed back in the day, and easily available components for self-building are of the high ...

Is there a bike co-op in your city? When I ran around on a ratbike like that, it was because I just got whatever people had laying around and stuck it together as cheaply as possible, usually with no thought about anything other than what was directly in front of me at the time. I needed a wheel that would roll, and once I put it on, I didn't think about it ...

A fixed gear bicycle (colloquially known as a "fixie") is one that whenever the rear wheel is turning, the pedals are turning. If your bike has this property, it is a fixed gear bicycle. If you can allow the rear wheels to turn without the pedals turning (i.e. coast without the pedals turning), your bicycle has the ability to freewheel. In a fixed gear ...

A fixie and a single speed are both similar in that they only offer a single gear that you can use to make the bicycle move. The difference is that a single speed will allow you to coast without turning the pedals while a fixie will require that you pedal the bike in order for it to move. To test if you have a fixed gear bike, flip the bike over give the ...
