RockShox Charger Damper Upgrade Kit
Best suspension refinement for riders seeking improved comfort and control.
This is the smartest way to breathe new life into a capable but aging fork. By swapping out the internals, you gain professional-grade compression tuning that transforms how your bike tracks over rough terrain. You’ll have to get your hands dirty with a rebuild, but the resulting control is worth every minute.
