Very rare Larivee Cycles track frame and fork. From the limited information I received he is a small builder located in San Jose, CA. I would guess this is from the 1980s? Not really sure. It is beautiful and in excellent condition. It measures 56cm center to center on the seat tube and 53cm center to center on the top tube. 27.2 seat tube inside diameter. 120mm rear spacing. Italian threaded bottom bracket. Zeus 2001 rear drop outs and fork crown. Reynolds 531 fork blades and Columbus tubing on the frame.
