Yamaguchi History

Every Yamaguchi bicycle is personally hand-built by Koichi Yamaguchi who gained his mastery of the craft during the years spent as Master frame builder for the legendary "3 Rensho" company in Japan.

In all, Koichi spent over four years building frames with 3 Rensho, mainly for professional Keirin riders, the most famous being ten-time Sprint World Champion Koichi Nakano.

In 1987, he realized that it was time to bring his unique vision of the frame builder's art to the public, and came to the United States where he founded his own company.

Koichi began working with the US Cycling Federation as National Team Mechanic in 1988, and, in 1989, he began making prototype frames for the US National Team and became the lone official framebuilder of the United States Olympic Cycling Team.
