The Invitation for Cycling by Mr.Gami

Part 62: Kaisei in 2005




Here is the catalog of Kaisei in 2005. Now, Kaisei is the only frame tube maker in Japan. 10 years ago, there were two big makers Ishiwata and Tange as the frame tube supplier.
Kaisei was established by a director of Ishiwata who inherited the business and the facilities of Ishiwata when Ishiwata went bankrupt. The brand names of Ishiwata such as 017, 019, and 022 were also succeeded.
I suppose that Kaisei has supplied their products to mass-production maker, and the NJS frame builder who has made track racing frame for Keirin athlete or amateur. Of course Kaisei tubes are also used for touring bicycle of ordinary cyclists. The frames of My Nakajima randonneur (700*35c) are Kaisei 019.

The catalog is A4 size 14 pages, was distributed to customer at the Kaisei booth of International bicycle exhibition.
