SUS YOYOMECHANICS - Transmission Cross Ratio

(This is a machine AI translation from Japanese. We will replace it once the English description done by our staff is ready.)

SUS's wish has come true with the undersized bimetal.

It is an undersized bimetal model with a wide stainless steel rim and a small, wide body. Although the project was once abandoned due to the trend of the market, we have been constantly brushing up the product behind the scenes and finally realized its release.
As the manufacturer comments below, the rim weight is extremely heavy in relation to the body, creating a power that is disproportionate to the petite size in a good sense. It goes without saying that its power is more than its appearance and numerical impression.

Comment from the manufacturer

The concept is "Wide & low".
Smaller diameter and wider.
The undersized bimetal was a product that SUS wanted to make (and will continue to make). In fact, we had made a drawing before "Transmission (Monometal)," but it was put in storage due to the atmosphere that undersize was almost completely out of trend at the time.
However, we could not give up and continued to make drawings while constantly filling them with our know-how.
The transmission that went on sale earlier was well received, and we decided to commercialize it as "Transmission Cross Ratio," an undersized bimetal.

The concept of the bimetal is exactly as a "custom car that can be anything," and as a yo-yo that is a cross between two different materials, it has been developed as a "Close-ratio" product.
The name "Cross Ratio" is derived from "Close-ratio".

Close-ratio is a customized yo-yo with a small difference in gear ratio, which is adjusted for the better part of the engine output for racing and various competitions.

The rim weight is approximately 50g, which accounts for 76% of the total weight, which gives it a rotating power that is hard to believe for an undersized rim, and a wide body. Please take a look at how this model, which may seem like horseshit if you look at the specs alone, is put together.

The color variations are again based on a custom model of a certain car model.
