Update on the Acerbis Rally Pros - to be honest, I'm not terribly impressed w/ them.
Great at deflecting branches/trees/small children.
However, if you take any falls in really gnarly/rocky terrain, it seems like they bend pretty harshly about half the time.
Kind of a PITA to have to rip them off trail-side to re-bend because they're bent so badly I can't fit my hand between them and the grip
Anyway, I think for the $$ they'd use thicker, or a stiffer grade, of aluminum. Will look elsewhere if these really tick me off over the long run...
