Oops. What is the deal with tankslappers like this? Weak forks set up a harmonic, or is it the headtube?
And does a steering damper guarantee (or almost guarantee) that this kind of accident will not occur?
A friend told me about how your brakes will need a pump after a tankslapper, due to flex in the front end (wheel, rotors and forks I think) pushing your brake pads in.
Pardon if a repost.
