RockShox SID SL Ultimate BRAIN

The RockShox SID SL Ultimate BRAIN incorporates a race-tuned Brain Inertia Valve with Position-Sensitive technology into the all-new RockShox SID SL chassis.

New Position-Sensitive Brain technology provides more platform support while maintaining small bump compliance and chassis balance, making this the most efficient BRAIN yet.

Position-Sensitive technology allows riders to sag into the fork 15mm for a balanced ride, providing supple small bump compliance and a firm pedaling platform without the need for a remote lockout or levers to flip.

All new SID SL Ultimate Chassis features a machined alloy crown to shed even more weight while increasing stiffness.

• New Position-Sensitive tune provides an increase in platform support.

• New SID SL Ultimate chassis features increased stiffness, lighter weight, and reduced friction.

• Torque cap compatible for stiff dropout/hub interface.

• 100mm travel, 44mm offset, 110mmx15mm hub spacing.
