Were early 90s Trek Carbon Composite frames "carbon wrapped aluminum" ?
Trek sold some Carbon Composite frames in the early 90s with three main tubes of carbon and the rear stays were aluminum. Talking with a friend, he said the tubes were actually carbon wrapped aluminum and not only carbon. I looked in the catalogs and they just say "carbon composite". Anyone have the skinny? I'm specifically interested in the MTB frames though I imagine the road and MTB frames are the same kind of construction

Thanks, I have one here too but didn't think to pull the seat post. I suspected the tube were full carbon just based on how they sounded but wasn't sure after talking to my buddy.

A few companies did use carbon-wrapped aluminum tubes for some of their bikes in the 1980s---Raleigh, for one. Not Trek, though.

The Treks are not carbon-wrapped aluminum. A lot of seat posts were done this way. The Trek Composites were not, and once Aegis was done with their work for Trek, OCLV was it.
Some of these composite frames could be built incredibly light for the time. Like 17.1 lbs.
