Yes, this thread is more like trashing the ideas I have, given that I am not too familiar with the technical side of these modern bikes. So far, I always ended up like what you say, I might be better off looking for another used road bike.

I bought this bike during covid years and it was long time available despite all bike stuff going up in price and scarce, as we all know how it was. But I guess it makes sense, TT bike would be the last thing people would look to buy when locked in their homes
I got it for less than it was advertised and after riding it a bit in the city (Toronto, Ca), I took it to Europe where I spend most biking seasons. When cleaned up, the bike looks newish and is like a little Ferrari and feels like that too.
In Europe, I ride in the region where it is quite rare to see higher end bikes, never mind TT style, which is quite exotic. I don't mind to admit I like this exclusivity and put up with some discomfort while riding the bike. I was only worried if I would be able to ride in that aero position at all but it turned out, I can. I figured if I found it too uncomfortable, I could resell the bike in Europe and likely even make money on it.

I brought the bike to a bike shop in nearby bigger town and the shop owner liked it very much but expressed opinion, that whoever sold me the bike put those shallow rim wheels on it for the sale, that this bike must have had deep rims. And indeed, these days, this bike type always comes with deep rims and disc brakes. I admit that nowadays the bike looks out of place without them, but don't think the seller put cheaper parts on the bike before selling it, that's how the original bike was manufactured in 2010. Everything on the bike is still original and is in a very good shape. When I took it apart for cleaning and checking it over, I could tell the bike wasn't dismantled for some time. BTW I took apart those shift levers for cleaning the sweat corrosion on the aluminum parts and found, it is not a job for everybody. That index shifting mechanism is quite complicated.

alcjphil thanks, there is not much info around for the training background, most of us only see those bikes in races.
I imagine, many owners of these TT bikes don't ride the life out of them, they are a bit awkward to use in urban, or even outdoor setting on most roads. Even with hands on bars in position for braking, it is not the same as on the classic road bars. I ride the bike in Europe, on small roads between villages that see little traffic and so I am able to go down into aero position on the bars for several kilometers even. I've personally seen owners of TT bikes in the city who got them out of some enthusiasm and they didn't see much use.
