In full version, with 18mm rubber, 6.5mm shaft and rigged with fishing line. The B 28 features an advanced LEADER handle, with an aerospace-grade aluminum tubular barrel with a V-shaped reduced friction guide along its entire length. Special shape that provides rigidity with minimal weight and positive buoyancy of 3.7 gr/cm. The thickness of the barrel wall around the perimeter for greater rigidity is not uniform (1-1.45mm depending on the stress point) and differs from the others.
