What's your top speed?

most ive hit on fixed is flat 30mph and 35mph downhill but ive done 59mph on my road bike but this was all when i was riding every day and not spending more time on my bmx than anything else
??

I find 71 GI about right for cycling pretty much everywhere. I think I average about 17-18 mph on the flat when riding at a comfortable cadence. Though this is a SS not a Fixed.
More like 20 mph. :)
