Fit Shaft GEAR - Normal Spinning #5 Medium (31mm) Innovative flight and shaft system The "push in" system provides easy insertion of flight into the shaft These one piece spinning shafts will allow your Fit Flights to spin out of the way of incoming darts The fit flight system prevents "Robin Hooding" which will lead to increased scoring These shafts will have a similar feel to the traditional plastic shafts but will last much longer becuase there are no plastic forks to break
