Hey, I read somewhere that if you touch your knees to the top tube, the shimmy will stop. I also heard that the lighter your bike (or wheelset) is the worse it handles. Any truth to that?

some good turns. In the numerous times I've been down this particular
road I've never seen or experienced a wobble.
I witnessed at least two Master's riders develop wobbles on the same
stretch where the 3/4 crash occured. One very experienced rider took a
foot out in anticipation of going down, but didn't. The other pulled it
out somehow too. I know one of them was riding a very deep section
carbon wheel.
I don't think this course is going to go away soon so I'd suggest to
everyone coming to the CCC in 2005 go out and do some high speed
testing. I personally don't need to see that kind of carnage again.
And to all those that were involved I wish you a speedy recovery.

The key in Erik's message is: "keep your arms and shoulders relaxed"
My worst wobbles were last year at a race in the Manchester velodrome.
I Got sandwiched by two riders and my reaction (besides trying to
backpedal) was to grip the handlebars tighly. As the wobbles started, I
freaked out and gripped the handlebars even tighter, which made the
wobbles way worse, until I slowed down enough. I immediatly thought for
sure there was something wrong with my bike, but one of the coaches told
me it was from the death grip I applied on the Handlebars.

It's completely possible some of the people in that CCC stage have never
decended so fast before. It's very hard to come by such a huge decent.
Anyone in the PDX area that hasn't done it yet, I'd suggest going down
Bald
Peak. I forget the name of the road, but it ends right at that store at
the
bottom of the hill. You can't miss it -- it's completely straight,
insanely
steep, and you will go faster than you've ever gone before. It's well
worth
riding for the experience. Keep your arms and shoulders relaxed. Be
careful, it's almost like a roller coaster ride.
I wish everyone a speedy recovery from the crash. Hope this message
helps
at least one person.
-Erik
