Specialized is advertising a "Future Shock" component that I've seen referenced now in a couple of recent threads. According to their marketing, it is smoother because it is above the head tube and the wheelbase doesn't change.

I've been trying to give the idea the benefit of the doubt and keep an open mind about it, but I can't see any reason mechanically for there to be much difference with the shock in the steering tube vs a shock in the fork. The weight of the bike pivoting on the rear axle, the bike itself jarring more with the new future shock, and that's about it as far as I can see.

Yes, the wheel-base changes when shocks on the front fork compress, but it's what a fraction of a mm? Compared to a change of reach when the future shock compresses. I don't see how either effect improves or degrades handling more than the other.

So geek out and explain why this is advantageous. Or is it a gimmick?
