Most of those bikes will be 26 inch wheeled hardtails.
They will have inner tubes.
They will have normal sized tyres.
They won’t have dropper posts.
They will have double or triple chainsets.
They will be 9 or 10 speed.
Typical MTB users are very casual users who ride along towpaths, cycle to the local park with mates, cycle round the lanes close to where they live, cycle occasionally off road on common land/national trust/forestry commission type stuff.
It’s only bike geeks and enthusiasts that fret over the change to 11 speed, whether to go 1x, 140mm or 160mm frame for the new trail bike build, what brand of dropper post, tyres for every occasion, strava, plus size tyres, 650b or 29er, carbon or titanium, etc etc…..we are but a small collective niche in a massive sea of short travel Alu hardtails!
