RockShox SID DebonAir Spring Shaft

This is the simplest way to fundamentally change how your bike handles without buying a new fork. By swapping out this internal shaft, you gain the ability to tune your suspension travel for specific trails. It requires a bit of mechanical patience, but the payoff is a ride perfectly dialed to your terrain.
