Common questions
Can I adjust the rebound on these shocks while riding?
The rebound adjuster knob is positioned for easy access, allowing you to tune it without tools during stops or while parked, making on-the-go adjustments convenient.

Preload adjustment allows you to set the sag for your weight and load, while rebound adjustment controls how quickly the shock extends after compression. Together, they offer comprehensive tuning for ride comfort and handling across various conditions.
