Just some idle thoughts over the mornibg coffee:
I might go a bit further and propose that professional players are actually quite bad for the everyman experience of sports such as mountain biking. If it hadn’t been for the lightweight “drillium” phase, driven by racing and marketing, we would have been riding full sus, larger tyred bikes long ago.
Likewise the plethora of big bikes that were produced in the josh bender phase.
As fas as i can see, for the majority of people (those without a fleet of bikes);
Pro riding breeds highly specalised machines to do best in the niche that contains money. Marketing and advertising then drives sales and the sport lurches toward that niche. Jo public sees ultra light racer or 40lbs sled and buys a cheap version. Cheap version is even more heavy/skittish/uncomfortable. Jo public gives up.
Currently we seem to be back to all-round bikes capable of long days pedaling toward the horizon. The proliferation of comfy, very forgiving bikes appears to correlate with a boom in MTB numbers.
