There's an ancient Chinese curse (at least so the internet has told me) that says "may you live in interesting times." Whether a blessing or a curse, these are interesting times. A short while ago the question was whether 11 speed would have massive uptake (of course it would, of course it did - although Mike and I are both still on 10 speed for a few weeks more yet), now the rate of change has increased exponentially, mostly having to do with how you slow down more than how you go fast. Of course, the impact that how you slow down has on how fast you go is a prime consideration.
I'll admit that I've slowly been coming around to using discs for cross, the transition to which has been eased for me since, after all, it's my job to build and ride crazy nice wheels and learn how they work. The emergence of road disc looks all but inevitable at this point, and if Mike has become as big a fan of tubeless as he has in the amount of time he has (the old Life cereal commercial comes to mind: "let Mikey try it, he hates EVERYTHING!") we're fairly bullish on that as well.
Parameters that weren't a consideration just a short time ago are THE parameters now. Interesting times, indeed.
