The RockShox Flight Attendant Charger RD2 Upgrade Kit transforms a compatible SID fork into a fully automatic electronic suspension system. Rather than relying on handlebar remotes or manual levers, Flight Attendant uses an accelerometer to detect your pedal stroke and terrain in real time, automatically switching the fork's compression mode for maximum efficiency when climbing and full openness when descending.

• Converts compatible SID forks to Flight Attendant automatic electronic suspension
• Charger RD2 damper with electronic actuation replaces the existing right-side damper
• Flight Attendant detects pedalling input and terrain — switches automatically between Open and Firm
• No handlebar remote required — the system manages itself
• Battery and charging hardware included

Flight Attendant responds faster than any manual remote, and because it operates continuously without rider input, it catches transitions — like a sudden steep descent mid-climb — that a manual system would miss. The Charger RD2 damper is purpose-built for electronic actuation and delivers consistent, precise compression switching across its full operating range.

Compatibility is specific to certain RockShox SID fork generations. Confirm your fork's model year and revision against the RockShox Flight Attendant compatibility chart before ordering. Includes all hardware required for battery mounting and charging.
