I've been recently considering purchasing a vintage (10-20 years old depending on model) carbon fiber road bike. More than likely any bike would not be full carbon at that age but would have bonded aluminum lugs or something like that. My general question--being more of a steel man--is there anything I should know about/be concerned with regards to older carbon fiber road bikes? Should I run back to steel before I drop a few hundred dollars on something that could easily turn out to be wall art? Thanks for the tips.
