On a rim brake bike the brakeing effort connects the rim with the fork crown. A portion of the brakeing force is transferred through spokes but much goes around the rim to the contact patch.
I'm far from being up on my physics, but all I meant was that as far as lacing is concerned the braking forces are of the same nature/direction, albeit different in degree. At least I think that's correct...surely there's an engineer around?
