>>1592740TT bikes or even Triathlon bikes aren't that comfy for longer rides and also more dangerous in handling.
For a training effort, it literally does not matter what bike you are on as long as you blow the same watts.
Other than that it's weird indeed that people spend thousands on drop bar "super bikes" which are so much slower than TT bikes. I guess TT bikes look too radical and get rejected by the mainstream. They are not "traditional" so people rather ride on expensive but slow bikes.
