RockShox SIDLuxe IsoStrut Rear Shock 80mm Travel for Trek Supercaliber

The RockShox SIDLuxe IsoStrut Rear Shock represents a significant advancement in rear suspension technology, engineered exclusively for the Trek Supercaliber 2023+ A1. This innovative component is seamlessly integrated into the bike’s frame, enhancing structural integrity and stiffness while effectively reducing overall weight. Its streamlined design simplifies the pivot mechanism, delivering a clean and efficient suspension system that elevates cross-country riding performance to professional standards.

With 80mm of race-tuned suspension travel, the SIDLuxe IsoStrut offers exceptional responsiveness on demanding XC trails. It features two distinct compression settings: Open for smooth, reactive suspension movement, and Lock for a firm, rock-solid feel that maximises power transfer during intense pedalling efforts. Developed in close partnership with Trek, this rear shock perfectly complements the Supercaliber’s lightweight, aggressive geometry, ensuring riders experience fast, controlled, and confident handling across varied terrain.

Every aspect of the SIDLuxe IsoStrut is designed with the serious rider in mind. By reducing the number of pivots compared to conventional full-suspension systems, it minimises maintenance requirements while enhancing pedalling efficiency. Despite its lightweight construction, the shock maintains robust durability, making it an ideal upgrade for riders seeking to optimise their bike’s performance without adding unnecessary bulk. Whether for competitive racing or dedicated training, this rear shock is a precision-engineered component that significantly improves mountain bike dynamics.
