Eric,
"Stem Planing" You might be on the something...I wonder, with
insufficient fastener torque, if one could induce brake lever planing
or handlebar planing.
I have an old Guerciotti Aluminum (I belive it was made by Alan) that
has a 1" threaded, all aluminum fork...think about this...the steerer
tube had the same outside diameter as a steel fork AND the same inside
diameter as a steel fork but made with a material that is 1/3rd as
stiff. Fork planing! No wonder I used to be so much faster....
