I just got another bike off one of my friends, and I haven't decided if i'm going to eventually turn it into a fixed gear yet or not, but it has the quick release axles on both wheels. The wheel has a cassette on it, so i know if i was to turn it into a fixed gear, it would need a whole new hub anyway, but until i decide, I could always just turn it into a single speed, my only concern, was whether or not the axle holds tight enough to keep the wheel from moving when i've gotta start pedaling in a higher gear than i do now. I know on my fixed gear i've gotta tighten the bolts pretty good to keep the wheel from moving, I wasn't sure what you guys thought about it, I think the only times i've had trouble with it moving was when i would skid, so that might not be a problem if it wasn't fixed on this bike, just curious what you guys thought,
