the road was pretty good and dry.
no potholes on there.
the first time i notice the wobble i used the powertap front wheel.
so, i suspected he was the problem. so i changed him to the ksyrium sl.
well, i think it's didn't helped me...
i heard that the r3 is known for this kind of problem.

this is the descent where i crashed (i didn't make this vid.)
you can see the place were the accident occurred in 3:36 to 3:50
