Yes, we talked about it already. Magnesium lower castings might not hold up
to the tension forces incurred by placing the caliper in front of the leg.

Which of course is [censored]. Fatigue is something you can design for and
eliminate.

damned right - you put the caliper behind the fork!!!

User error *must* be designed for because it cannot be

true. just like steering over-ride mechanism that stops me crashing
into trees? or maybe you mean the ankle chain that stops me leaving my
sofa because the minute i jump on my bike, i'm exposed to all kinds of
danger my sofa does just not offer? i mean, that's /real/ risk elimination.

:-) Right! That's EXACTLY why all front cantilever studs face
backward! Right, Jim?

After all, we _know_ nobody can safely design members in tension! ;-)

what kind of engineering professor are you frank? it's incredible to me
that someone that dare to teach this otherwise exacting discipline has
the balls to deliberately ignore application data that is so public and
so commonly used in critical systems design. are you for real?
