i don't quite understand the argument here.

i got my $1.50/pair tektro v-brakes (includes generic pads) and my $2 set
of general duty jagwire housing (includes brake cables) off china's taobao.

set 'em up, and can squeeze the brakes and skid to a halt if i desire. that
means freezing the wheels up, right? so what the hell will compressionless
housing do for me?

ok.....put a $9 BB5 on the rear of a new disc-only frame. what a piece of
carp! replaced with $19 BB7. much improved over the BB5, but in no way
equal to the cheap tektros.

personally, i'm waiting for technology to solve yet another non-problem.
i'm sure pretty soon we'll get a voice activated cell phone ap that will
activate wireless disc brakes. pretty nifty! only drawback is you need
to use your v-brakes to stop first in order to safely access your cellphone.
