We like the RockShox Charger 3 RC2 Upgrade Kit for its ability to transform our existing RockShox Lyrik, Pike, or Zeb forks into a top-of-the-line suspension component. Complete with low and high-speed compression and a low-speed rebound adjustments, the RockShox Charger 3 RC2 Upgrade Kit allows us to tune our fork to perfection.
