Give your all-day trail bike the firepower it needs for rugged terrain, plus the efficiency of an automatic suspension system.Flight Attendant algorithm uses a suite sensors to read rider and terrain inputs to anticipate the perfect suspension position. High-flow main piston reduces high speed compression damping, eliminating hang-ups and allows the wheel to easily get out of the way on hard impacts. DebonAir+ air springs maximizes fine-tuning potential, allowing you to tune both the negative and positive air volumeHydraulic Bottom Out kicks in to restrict the flow of oil within the last 20% of travel Can only be used with the complete 3-part Flight Attendant system (fork, rear shock, power meter) AXS battery and charger included SRAM Model ID: RS-SUPER DLX ULT FLT ATNDT-C2
