1987 Sunn Alu Expert

I bought this frame to a friend who had raced it in the past. It had been broken and had a horrible repair, so my idea was to repair it and take it back to its original condition.

But I changed my mind when I found out that this repair had been done by the mythical catalan motorcycle tecnician Antonio Cobas (https://en.wikipedia.org/wiki/Antonio_Cobas). Then I decided to keep the horrible repair and the added "gusset" and stuck a decal with the logo of his brand (Kobas).
Imported by GT BMX EspaƱa, Sunn bikes were the most desired BMX bikes in 1987 and 1988 in Spain. I built it with era correct parts that could be found in Spain on those days.
