Crafted from an ultra-durable material and featuring our full-lock anti-Robin Hood design, the new L1 Standard and L3 Shape Replacement Flights are built to withstand heavy play, exclusively for the L-System shafts. They are now sold as single units (1-piece), they allow you to replace only the flight that gets damaged instead of purchasing a full set of three. The single-unit design also makes it easy to mix and match individual colors to create a completely customized setup.
