About the suspension position.
On my 21 there is two position for fitting the suspension, one in the middle of the tube, the second underneath the DE Dion tube.
The suspension was originally fitted on "underneath" setting
It seems the position in the middle of the tube is a slight angle compared to the underneath position which is straight down
Why 2 positions? Effect on handling? reduce size of damper?
Is it something historical?
Cheers
Jack
