I have extensive "flexing" from the flevopivot mount to the rear frame
clip-mounted), so I can't determine if anything else are flexing until that
is fixed. I would suspect the Dirk's pivot (the flat plates) after seeing
his weldings (good!). On my bike the rear fork (a pleonasm? The fork!) is
the weakest point - I'm fixing that with 10*10*1 tubing from dropouts to
seatmount. I'm going to make a tube that fits the flevoaxel exactly in a
lathe, and braze it in the rear frame, but maybe I can't eliminate every
last bit of flexing. I wonder if flevobike have the same problem - I used
mild steel and the flevo way with enforcements plates :
http://www.hpv-klub.dk/selvbygger/Flevoracer/e-fr09.gif - the holes in the
rear frame are bound to be eliptical in time.
