It is dangerous to ride without brakes on the street... this is why my fg road bike, fg touring bike, and fg mtb all have them.
Was out on my road bike this evening and I can't imagine having to do a brake less panic stop at 45kmh.
When I am on the touring bike and carrying a load of gear there is no way I am going to be able to un-weight the back wheel and on descents the momentum created rates brakes... two of them.
The mtb is the only bike that I would ride brakeless as it has such a low gearing.
