This is a custom-made frame set.

Therefore, if you are considering purchasing, please contact us directly. Please let us know your desired size, frame color, and other preferences.

After realizing the amazingness and benefits of the latest road bike technology, we wondered if we could incorporate this technology into traditional road bikes.

Of course, this also incorporates our cherished concept of "long-term, careful use."

This was the impetus for the birth of our original road bike, "KOGO."

The model name, KOGO, comes from "Kogo," the name of the area where Grumpy is located.

Kogo also means "metal horse," which was the perfect name for a bicycle.
