The cable manufacturer should be able to answer what is the minimum bend radius. This is a very typical specification for industrial cables, especially those marketed/intended for continuously moving/bending applications. For home audio purposes, this doesn't seem relevant.
Bending limits are determined by a combination of the thickness and hardness properties of the insulation/jacketing, and conductor diameter, construction (stranded/solid), and material (copper/aluminum/silver).
I recommend avoiding situations where tight bends are necessary. If tight bends are necessary, Morrow Audio (and similar non-braded individually-insulated multi-strand designs) will perform well - because the strands are not bound together, and free to move inside the bundle without strain or binding.
