I sort of agree with TINAS- I have one, I ride it on actual genuine off road so feel it’s justified. But using one as just a road bike a) is making life difficult for yourself b) horrid and c) daft.
I bought mine to cover some touring duties as well, so I wouldn’t disagree,
But I also use it about 50/50 on/off road for my local riding, it’s much better on the road than an MTB, it’s a lot better off-road than a road bike, just a different set of compromises, TBF some people buy fat bikes without living in the Arctic circle or the Sahara…
I was chatting with a fella at work the other day, who had changed the tyres on what he called his “CX bike” for 25mm road slicks @~100psi…
He did this as soon as he bought it, and has never actually ridden it off-road, I suggested then it was really more of a disc-braked tourer, this apparently offended him slightly, he sees it as more of a “winter road bike” (although he won’t fit guards) personally I can’t see the point of buying an off road capable bike and then adapting it to use it only on the road, he might as well have just bought a normal road bike…
“Gnarmac/Gravel/allroad” bikes sell because the brakes are generally better, and they still look/ride much like a normal road bike, a good chunk of the target market simply ain’t interested in the full spectrum of potential uses these bikes have, fair enough, I wouldn’t say they’re making life difficult or unpleasant for themselves, and it’s not all that daft really, they’ve just missed the point of such capable bikes a bit…
