The French company "LOOK" started as a manufacturer of ski bindings during the 1950s. Then 25 years ago they began to market clipless bike pedals. They have also been making bike frames for over 20 years. They were one of the first companies to build frames using carbon fiber construction.

I'm not familiar with any of the bikes or the specific models, but they still make frames and complete Road and Mountain bikes today.

Are you talking about an older 1980s or 1990s bike which you think may still have the original components?

Is there some reason you would question that it was not entirely original?

As I recall, the Shimano Exage components were pretty decent middle-level budget components from 20 or 25 years ago. And there were several different models within the Exage name. Certain ones were made for Road bikes and others for Mountain bikes.

Photos might be helpful to someone familiar with the older LOOK bike models.
