As far as mainstream MTB and road goes, more technology for the sake of it/sales is what I see coming. MTBs are going electronic sus already and gears will be very soon. More integration, apps, settings and faffery on the way ) The Trek Domane is good to see, not sure about the execution but more passive suspension in general would be useful. More integration like the Cervelo s5.
A nice 5-spd super-direct feeling wide-ratio rohloff-quality hub would be good. More development of cable discs maybe. Better bikes for real adventure / out-there use. The Honda mech-in-a-box – make that work for a 1×11 range and I’m in. I can see some high hurdles in that though.
Wider hubs, pivotless shock absorption, lighter more MTB/CX crossover approach that can handle drops and tech? I own a bike of the future! 🙂 and it looks like a 50’s/postie’s bike.
You can keep your 1.8s tho. I see much wider acceptance of heavier but wider rims and tyres before too long, on anything without bags of travel anyway.
