"SUPER SHIFT" was developed to shorten the stroke of FK8.
The extension pivot that extends the bottom of the rod of the genuine shift assembly is highly accurate, so it has sufficient durability just by inserting it into the genuine pivot part and fixing it with a grub screw.
The supplied fixing screws (4) are made with lock processing (loosening prevention), so it is not necessary to prepare a screw locking agent when installing the product.
By making the bottom of the genuine shift rod longer, it is possible to make an appropriate short shift (compared to the original, approx. 20% short).
If the extension is longer than this, the angle of the shift wire becomes stricter. As a result of careful consideration of long-term stable use and the appropriate stroke amount, we determined that the above extension is the best for the extension under the rod.
