Well shimano is wellknown for using other's ideas and then she patents them herself and sues other for using them. The cranks have bolts on both ends on RF new line. It is irrational to bolt a glued crankarm to an axle. Attaching a crankarm to an axle is not a patent nor outboard bearings. I never said that RF was unique or blah blah blah....i just said its a radically new design in comparison with ISIS and square taper, and by the way i didnt mention XTR style or octalink simply because they are letter designs
