curve type ?

is it possible to convert a Bezier curve to a path curve ?

I did a chain bicycle
and it deforms along the Bezier curve
but along a path curve it does not deform

happy bl

here is pic for the 2 curves shape

see the difference deform between the 2 curves

and why there is no spline resolution on one Bezier curve and there is resolution the other one?

if I use path nurb then there is minimum deformations!

the old Bezier curve seems to have min deformation of links
but the Bezier I did which change shape does have a lot of deformations!
but not I use path curve !
