it's just that you can't lock a wheel if it's being turned by it's 'engine'
But you can stop the engine at any time. You're applying retarding force, aren't you - so if the tyre suddenly has less traction force than the retarding force you are applying, then you'll skid - as demonstrated by our friend on the right --->
So you are suggesting keeping turning the wheels to prevent skids - well fine, but the net effect is exactly the same as braking.
i'm surprised you have a dead spot, maybe you should work on your souplesse a bit more.
Everyone has a dead spot. Better pedalling technique lessens it, but it's still there. Brakes on the other hand are constant all the way round unless your rim's dinged or something.
if the surface changes to one with less grip(manhole cover)the wheel would instantly lock if a brake is being applied but keep turning if a fixed wheel.
If you are slamming on the anchors hard, then yes - but the same would happen on a fixie if you could apply that much braking force (which you couldn't I bet). I never have a problem with skidding ever unless it's a) icy or b) very very muddy off road.
i'm not dreaming it really happened i was there, have witnesses and everything
What happened? Were you talking about a specific case?
who is saying it's technically better?
You were saying that you wouldn't ever lock wheels when riding fixed but you would all the time when using brakes...
