Gear ratios for no brakes riding...

http://www.sheldonbrown.com/brakturn.html

it seems to me that brakeless riders are unwilling to concede that it is more dangerous, that they would be safer with a front brake, but that they do it anyway

I would also be safer with a helmet, 2x mini D, cycle insurance, wearing a condom, not eating after 8pm, drink less, wash fruit before I eat it, catch it kill it bin it, dont step on the cracks, remember remember the 5th of november, avoid gypsies, double lock the front door, mind the gap, cover my pin number
