The RockShox SIDLuxe IsoStrut Rear Shock is a revolutionary rear suspension component designed exclusively for the Trek Supercaliber 2023+ A1. Seamlessly integrated into the frame, this shock enhances the bike’s structural integrity and stiffness, all while reducing overall weight. Its innovative design simplifies the pivot layout, providing a clean, efficient system that elevates your cross-country riding experience.
With 80mm of race-tuned suspension travel, the SIDLuxe IsoStrut delivers exceptional performance on the most demanding XC tracks. Riders benefit from two distinct compression settings—Open for smooth, responsive suspension and Lock for a firm, rock-solid feel when you need maximum power transfer. Engineered in close collaboration with Trek, this rear shock perfectly complements the Supercaliber’s lightweight and aggressive geometry, ensuring every ride is fast, controlled, and confident.
Every detail of the SIDLuxe IsoStrut is crafted with the racer in mind. The design reduces the number of pivots compared to traditional full-suspension systems, which means less maintenance and improved efficiency. Its lightweight construction doesn’t compromise durability, making it an ideal finishing kit component that enhances your bike’s performance without adding unnecessary bulk. Whether you’re competing or training, this rear shock is a game-changer for serious mountain bikers.
Is the SIDLuxe IsoStrut compatible with all Trek Supercaliber models?
This shock is specifically designed for the 2023+ A1 Trek Supercaliber, ensuring perfect integration and performance. Compatibility with other models may vary and is not recommended.
How does the two-position compression damping work?
The shock offers an Open setting for smooth, active suspension and a Lock setting that firm ups the shock for efficient pedaling and power transfer on smooth terrain or climbs.
Can this rear shock be used on e-bikes?
Yes, the SIDLuxe IsoStrut is e-bike approved, making it suitable for electric mountain bikes that require durable and responsive suspension components.
What maintenance is required for this rear shock?
Thanks to its simplified design with fewer pivots, maintenance is reduced compared to traditional full-suspension systems. Regular servicing according to RockShox guidelines will keep it performing at its best.
