It used to be oh so simple, just road bikes and mountain bikes. In the road category, we were limited to two faithful options: a winter bike and a race bike. Cyclo-cross existed too, in a muddy no-man’s land, but there was little mixing of the on-and off-road riding genres.
Then came endurance and aero bikes, then gravel. The latter has been a buzzword for the last half-decade, and for good reason.
