It's not about how I feel. It's about fact.

The fact is that if you've ridden for a while you understand that the innovation ("a new method, idea, product, etc.") happened many years ago.

I was kind of late to the dropper party (notwithstanding my Hite Rite way back when) but still started riding with one in 2005.

That's why your "the best innovation in recent years for mountain biking" bit made me chuckle.
