Only problem is, when Trek first came out with their carbon fiber frame, the glue they used for the aluminum bottom bracket wasn't that great, and their frames kept cracking about 1 inch above the bottom bracket. To tell the truth? I think that the Columbus steel frame rides better than carbon fiber.
Not that it has anything to do with the OP, but you're referring to the 90s Trek Y bike. Great bikes. The rear shock detachment and the cracks were a result of the frame being engineered for a certain design limit for the ultimate in racing competition to minimize weight and some people exceeding that. Most Y frames never detached or cracked. They learned their lesson and upped the mass of the frame in 98 for that select few who were beating the living bejeezus out of them. I like the original Y series the best. Never had a problem with one yet.
True carbon is light and absolutely rigid, so of course a heavier inertial mass frame made of metal (flexes) will absorb energy have a different feel to the ride.
