The frame also comprises a number of connecting elements, each located between a pair of blocks and each having a pair of opposed convex lateral surfaces and a pair of first ridges projecting perpendicularly to the core axis. Each block presents a pair of opposed concave surfaces designed to mate with respective convex surfaces on the connecting elements, and two pairs of second ridges, each facing a respective first ridge on a connecting element, so that, when the bow is flexed, the second ridges of each block on one side of the bow contact respective first ridges on the connecting elements.
