BSF Products has released the F-spine, the signature counterweight of Hibiki Fugono, a member of Team YYR!
The F-spine is made from a single material, offering the unique ease of handling characteristic of such designs—allowing for simple operation with minimal effort. Additionally, this single-material construction has made it possible to  realize a lower price.
It was designed with the concept of instantaneous acceleration and deceleration to express Hibiki Fugono’s signature style: “control that accelerates the weight to top speed in an instant and brings it to a sudden, precise stop.”
