Let me see if I can spice this up a little bit
....
Below is what, in my mind, could be a tyre/asfalt interaction that could cause the formation of a raised trailing edge.
Like I said, this is commonly related to a too fast rebound.
It makes sense for the front wheel....The bike bounces back to fast raising the tyre from the ground, and when the tyre comes back in contact with the ground creates this kind of effect. But what about the rear tyre? If the bike is under acceleration it should have the opposite effect, right?
And what if you have a too hard compression setting and a too slow rebound setting? When you hit a bump the shock is not able to absorb the hit and kicks the bike up. The rebound, being too slow, makes the tyre lose contact with the ground. When the tyre gets back in contact creates the effect seen (again, under acceleration could be different in the rear tyre).
Also, if you do trail braking in the curves couldn't this be an expected effect?
