Understanding the Role of Linkage Kits in Mountain Bike Suspension
Before we explore the specifics of the FS01 FS Linkage Kit Black, it’s worth taking a moment to appreciate the importance of linkage systems in full-suspension mountain bikes. The linkage is the heart of the rear suspension, connecting the frame, shock, and rear triangle. It dictates how the bike absorbs impacts, maintains traction, and responds to pedaling forces. A well-designed linkage like BMC’s Advanced Pivot System (APS) ensures efficient power transfer while keeping the ride smooth over rough trails.
BMC’s Fourstroke bikes, known for their lightweight carbon frames and race-ready geometry, rely on such linkages to balance climbing prowess with descending confidence. The FS01 FS Linkage Kit Black is part of this ecosystem, allowing riders to maintain or adjust their bike’s kinematics. For instance, if your Fourstroke is set up for longer travel (typically 120mm or more in LT models), this kit enables a seamless conversion to 100mm short travel, making the bike snappier for cross-country racing or technical climbs.

As seen in the image above, the kit comes complete with all necessary components, laid out for easy identification. This includes the linkages themselves, a shock yoke, axles, bolts, bearings, and washers – everything you need for a full overhaul without hunting down individual parts.
