RockShox Rear Shock SIDLuxe IsoStrut Trek Supercaliber 2023+ A1

SIDLuxe IsoStrut Rear Shock

The all-new SIDLuxe IsoStrut is a frame-integrated rear shock built specifically for the Trek Supercaliber. By designing the rear suspension as a complete system, it preserves the bike’s structural integrity and stiffness while reducing weight through a simplified pivot layout. SIDLuxe IsoStrut offers two compression settings—Open and a rock-solid Lock—delivering 80mm of race-tuned suspension performance made to conquer the toughest XC tracks.
