Actually, I did, but remember I am an accountant and I’ve been told I’m wrong, by my brother no less. Regardless, right or wrong, my method has worked for me for many years. I’ve never tried the knees on the top tube method, it just seems too awkward to me.
From Sheldon Brown blurb on shimmy: “
Jobst Brandt reports that unloading the saddle without standing up will stop shimmy.”
More from Brandt: “
Shimmy that concerns riders the most occurs with hands firmly on the bars and it is rider generated by muscular effect whose natural response is the same as the shimmy frequency, about that of Human shivering. Descending in cold weather can be difficult for this reason. The rider's "death grip" only enhances the incidence of shimmy in this situation. Loosely holding the bars between thumb and forefinger is a way of avoiding shimmy when cold.”
