Interestingly, when switching between my bikes with the SL's and the ones w platform C's, the worn cleats feel less worn on the C bikes than the SL bikes.
Do a search, numerous users have had the pedal break at the spindle and slide off while riding. Application doesn't seem to matter, I've seen it firsthand on road bikes & fixes, but even more complaints from downhillers (they are probably the guys to listen to when it comes to pedal durability, unclipping, etc. Coming off a long drop can yank the beejeesus out of a pedal, super sudden torque) If it were just guys skidding or downhillers landing that'd be one thing, but that it has happened across a broad spectrum points to some inherent weakness where the spindle is attached to the body.
The upside is that Crank Brothers has awesome customer service and replaces broken gear without a fuss, plus their no doubt finding a fix for said problem as we type.
I'm a busted phonograph, but Time is the way to go for fixed, toughest & securest.
