RockShox Charger Race Day 2 Flight Attendant Damper Upgrade Kit | SID 35 C1-D1+ (2021+)

Charger Race Day 2 Flight Attendant Upgrade Kit – an intelligent upgrade for your SID / SID SL fork

Flight Attendant Upgrade Kit transforms your SID or SID SL fork into an electronic, fully automatic suspension system that independently selects the optimal damping mode: Open, Pedal, or Lock. This upgrade allows even a hardtail bike to function as part of the Flight Attendant ecosystem – analyzing terrain, pedaling dynamics, and rider input to maximise efficiency during sprints, climbs, and long endurance rides. It’s a new level of precision, customization, and speed that was previously available only on full-suspension setups.

Features:

• Smart suspension upgrade: designed for 2021–2024 (C1–E1) SID and SID SL forks, enabling modern electronic functionality without replacing the entire fork.
• Hardtail compatibility: the “Fork-Only” function allows the Flight Attendant system to work perfectly on hardtail frames, maximising pedaling efficiency.
• Automatic 3-mode control: the electronic Charger Race Day 2 Flight Attendant damper switches between Open, Pedal, and Lock based on terrain and riding intensity, with independent rebound adjustment.
• AXS ecosystem integration: requires a Flight Attendant rear shock and an AXS pedal sensor or power meter; adding more AXS components further improves accuracy and connectivity.
• Complete installation kit: includes the Flight Attendant damper, control module for SID / SID SL forks, SRAM battery, and charger.
