Here’s a few of my predictions:
Belt drive and internal hub gears will all be more refined, cheaper and more expensive depending on whether you go for the XTR or Deore version.
Fat-bikes will become the new niche when 29er’s become mainstream.
Someone will change the headset standard, circa 2016-17
Current 11 sprocket road cassette technology will make it to MTB
We’ll still be building wheels using conventional spokes, but carbons rims will be more common/ stronger/ more durable and cheaper.
I’ll still be riding a titanium bike.
