I know hard-core fixed-gear riders like to be known by their nuts, but from a practical standpoint the quick release makes great sense for those of us frequently shifting gears in hilly or mountainous terrain.
I keep getting told by members of the modern fixed gear crowd that quick release hubs aren't a good idea for fixed gear bikes. In contrast I place almost 30 years on fixed gears with only quick release hubs. I may have pulled the rear wheel crooked once or twice, but I did that with my road bike as well.
Similarly, holding fixed cogs on old-school freewheel-threaded hubs using a bottom bracket lock ring may have been less than ideal, but I only spun the cog loose once or twice in nearly three decades. I do prefer to have proper stepped threads, but straight freewheel threads allowed me to stack a couple of cogs many years before Surly's Dingle Cog came out. Yes, you shouldn't backpedal against the outer one, but it was there for forward locomotion. I wouldn't do it any more, but for a while the wild and free fixed-gear devotee had to scrounge. The subculture was so very sub as hardly to be visible.
The free-range fixed gear is a different animal from the creature of the velodrome. We make all kinds of mutations, some successful, some less so. Unrestricted by the rules, distinct stresses and closed environment of the track, we venture into all sorts of territory.
Tell me how it's gone for you, skewered or nutted.
