i have one brakeless fixed and one double braked fixed.
The brakeless is fun, but I don't get why more people don't run two brakes. All the smooth spinning and fun from a fixed gear with the easy ability to stop of two brakes.
just wish it wasn't a conversion, pedal strike is a ***** (i've had 3 hard hits in the past 2 days. not bad, but scary as hell)
