You are just demonstrating further that my first response was right. Just for fun, sit on the couch
and squeeze a tennis ball hard for five minutes. See that's so much easier than doing something real
like pedalling uphill. Perhaps if you had ridden mountain bikes downhill with different braking
system your "theoretical" views on their performance would have more credibility

Or you could consider the reality of physics. It's harder to pedal a bike uphill than to squeeze the
brake levers coming down hill. Or does sitting on the couch squeezing your tennis ball elevate your
heart rate and make you short of breath? ;-)

I've done 25 mile descents with lots of turns and braking, next to cliffs with fatally high drops if
one misses a turn. Does that count? Let's see, that was with cantilevers and with single pivot
sidepulls. The only discomfort I had was from bracing my weight against the bars.

Bet I can ride a bike up hill for longer than you can keep a tennis ball squeezed.

If you're talking about sqeezing the ball just hard enough to simulate the force needed to slow down
a MTB, my money's on Tim. I haven't ever finished a ride thinking "wow, my arms are wasted", but
plenty of 'em thinking "wow, my legs are wasted". In fact, the closest I've ever come to pumping out
my arms was on a road bike!

Tearing. The bead was made up of two steel wires and the rubber pulled off of them.

Oh dear, you are rather confused aren't you?

Your sarcasm here merely serves to highlight your ignorance.

I'm really sorry that the facts are not to your liking - maybe you better fabricate some new ones
that please you.

I'd had frequent aching hands and forearms from braking on long/multiple descents before I fitted
the Hope brake, and for my size, I have quite large forearms, and I do have a good strong grip
(that'll be from the rock climbing I guess).

Even trying to keep a small constant/slightly modulated pressure applied with the fingers, at the
angles applicable to braking causes hands to stiffen and ache.

I told you in the last paragraph, but I will add to that, 'they take a lot less maintenance to keep
at their peak performance than rim brakes'.

Locking a wheel when the bike is static or moving slowly is easy. Get that speed up some, then
achieving the same becomes more difficult, as well as obviously less desireable. Good hydro discs
can achieve the same braking force with less lever pressure, and deliver it ina more consistant
(rather than condition dependant) and manageable manner that with rim brakes.

I believe you are projecting.

Oh dear, that cut me deeply - see you when I get back from victim therapy, heheheheheh....

Indeed - when was the last time you considered dismounting and walking because your fingers were too
tired to work the brakes?

>In fact, the closest I've ever come to pumping out my arms was on a road bike!

Not surprising - longer descents with less loss to rolling resistance demand more braking. My
(non-zero) experience suggests this is a complete red herring - then again, I used to ring bells,
and still have strong fingers.
