I will preface this by stating that for the riding I do discs and thru axles don't make sense. They solve problems that generally didn't really exist. (For me) Thru axles are like the Bluetooth of the bike world. You never realised that you needed your headphones to be wireless until someone took away the jack socket on your phone. Hell, you never even realised that the Walkman jauntily clipped to the waistband of your hotpants was an encumbrance until your smartphone took over that role. And who carried a camera around with them 24/7? Sorry - I may have strayed off topic. My point is that the world is full of innovations that we didn't need until we were offered them. Discs and thru axles being a case in point.
