8. The bow of claim 1 , wherein the first non-planar riser plate and the second non-planar riser plate are concave;

wherein the width of the gap is smaller at a central location than the width of the gap is at a location distal to the central location.

9. The bow of claim 8 , wherein an outer surface of the first non-planar riser plate and an outer surface of the second non-planar riser plate are each concave.

10. The bow of claim 8 , wherein an inner surface of the first non-planar riser plate and an inner surface of the second non-planar riser plate are each convex.

11. The bow of claim 10 , wherein the inner surface of the first non-planar riser plate and the inner surface of the second non-planar riser plate define the gap.

12. The bow of claim 1 , wherein the first non-planar riser plate and the second non-planar riser plate are convex;

wherein the width of the gap is larger at a central location than the width of the gap is at a location distal to the central location.

13. The bow of claim 12 , wherein an outer surface of the first non-planar riser plate and an outer surface of the second non-planar riser plate are each convex.

14. The bow of claim 12 , wherein an inner surface of the first non-planar riser plate and an inner surface of the second non-planar riser plate are each concave.

15. The bow of claim 14 , wherein the inner surface of the first non-planar riser plate and the inner surface of the second non-planar riser plate define the gap.

16. A riser assembly for a bow, comprising:

a first non-planar riser plate; and

a second non-planar riser plate coupled to the first non-planar riser plate with one or more connectors;

wherein the first non-planar riser plate and the second non-planar riser plate define a gap therebetween, a width of the gap extending from the first non-planar riser plate to the second non-planar riser plate;

wherein the width of the gap varies in size such that the width of the gap at a central location of the gap is smaller than the width of the gap at a location distal to the central location;

wherein an outer surface of the first non-planar riser plate and an outer surface of the second non-planar riser plate are each concave.
