Vintage Kawamura Designed Carbon Frame 55 cm

Description

Vintage Kawamura Designed Carbon Frame. 55 cm. I have been unable to ID this bike. It has a very unusual texture to the carbon weave that is palpable.  The lugs are similar to some that i have seen but do not match any particular brand. The cable guides on the top tube are also unique. The only markings I can find include a serial number (80339) and a decal on the right chain stay that says, " Designed By Kawamura". My research indicates that Kawamura Designed bikes for several bike manufacturers. When found the majority of the components on it were Suntour Superbe plus some Shimano. The drop outs are Shimano Dura Ace. The headset is Shimano 600. I believe that the frame dates to around 1980. There are some nicks and scratches on the aluminum but the carbon is in very good shape. It requires a 68mm bb and 25.2 seatpost. 2000 gram weight.
The last picture shows the bike (only the frame is being sold) when whole.
