The Story
Cosmo Fit Shaft Gear in red are made from a polycarbonate resin to strengthen the stem at both the screw thread and the base of the top. These size 1 spinning red stems have a rounded top to allow the flight to rotate and the hybrid stem profile is concave towards the top of the stem, and a wider base where it screws into the barrel. The given length of these size 1 red stems is what is visible when the dart is fully assembled. Shaft length: 13mm
