Tauruck, we were in top form at BUB last year. All sorts of speed wobbles and crashes. It was so bad that the event was on hold cause both of the meat wagons were hauling folks to the hospital. The head guy, Denis Manning, came down to pre-stage and gave all of us a lecture on bike building and set up so we would not speed wobble. This is what he said.
First, make sure the wheels are in balance and true.
Second, be sure the wheels are in line with each other.
Third, the bike needs to be in balance. In other words, it should not want to fall to one side or the other 'cause one side is heavier.
Fourth, the aerodynamics should be the same on either side. One side should not have more drag than the other.
He might have said more and I forgot about it. This definitely is something to think about during the build.
