The PCS-12.2 features Park Tool's cam-actuated micro-adjust clamp design, which quickly and easily accommodates virtually any seat tube or frame. The clamp head also rotates 360 degrees, positioning all parts of the bike within reach. The stand's all-steel construction ensures maximum rigidity and stability, with super-strong glass-filled nylon composite fittings and top tube internals for extra dependability. The PCS-12.2 mounts to any flat surface.
