I have a 2014 CX comp and now only use it for circuit riding as a means to get fitter (with 28mm slicks) as I feel it was not really much good at any one thing that my other bikes could do. (apart from out and out road riding with slicks)
It is quite heavy and as a gravel / tow path / odd saunt through the woods, it feels initially fast but I think only because it is rigid.
Looking at times and going by feel, I am quite a bit faster on my lighter hard tail – but then again the HT cost considerably more.
Suppose it depends on what other bikes you have. If you have good quality mtbs and want to do a bit on the road, I’d get a road bike.
This is why I’ve bought a s/h road bike from here and am thinking about selling my CX.
