1987 Mantis XCR (team bike of Dan Diaz)

Richard Cunningham's attempt at maximizing the potential of two materials with a two-piece, two-material frame. By using a steel rear triangle bolted to the aluminum front triangle he eliminated the soft dropouts, tight tire and chainring clearance caused by fat aluminum tubing, made a light front end and a stiff rear end. A really beautiful frame. I think the front triangle might have been updated/replaced at a later date based on some of the details.

This was the bike of former pro and Team Mantis rider Dan Diaz. I think he had a nickname on the race circuit which is escaping me right now...
