The RockShox SID Ultimate is the premier cross-country suspension fork built for riders who demand speed, precision, and control across every mile of the trail. Lighter than ever and backed by a stiff 35mm chassis, the SID Ultimate holds its line when the pressure’s on—whether you’re charging a descent or attacking a switchback climb.

Equipped with the Race Day 2 3P damper, this fork gives you three distinct compression modes—Open, Pedal, and Lock—so you can adapt to terrain on the fly. The updated DebonAir spring delivers next-level small bump sensitivity and mid-stroke support for a supple yet controlled ride, no matter the conditions.
