I came off rollers once. The perception of speed makes it a strange experience. Your bike and body aren't moving, just the wheels and drive train, so there is very little inertia. You just stop. Far different than if you fell while rolling down the road @ 25 mph. As @
ksryder said, it's akin to hopping a curb, or less. Never hurts to look your bike over, but if you find any damage I'd suspect it was there prior to this.
