You know this may just be me, but it really pisses me off when people make obnoxious judge mental comments about my bike. ESPECIALLY when they shout them out the window of a car.
If I wanna run a freewheel and wear spandex, who the hell are you to tell me I shouldn't. Instead of trying to defend his ride by pointing out he had a fixed cog on the other side of his hub, he shoulda called you out by pointing out that maybe YOU should be riding fixed.
Oh yeah, and spandex is sexah!
