No need for this kind of negativity.
Okay okay…when I say “ditched” I may be overstating somewhat. “Retained for spares”.
I was once called a biomechanical mess by a researcher in the area (I was not one of her subjects), maybe I should look into one of these bikes…
Depends who you are as a rider, really. Some people’s one bike solution would be a road bike, personally I love having an XC hardtail. For me half my riding is on trails, then gravel and pavement would be like 25% each. An interval workout on a mtb has the same training effect as on a road bike, and I find it much more comfortable (especially when your local roads are terrible). I use my xc bike for 99% of my rides. Only time I’ve ridden my road bike this year is in one race and then whenever I have to lock it up outside. (my road bike is only worth $300, so I care much less if it’s stolen).
