I try not to seem jaded, or to be condescending to the younger generation. ;-) However, when you've spent enough time with anything--including bicycles and bicycling--you realize that there really is "nothing new under the sun." To wit:
About twenty years ago, suspension was the great "new" development in bicycles. But, as you can see, it had been done a century earlier. It was revived at various times: If you're a bit older than I am, you may have ridden a Schwinn or Columbia balloon-tired bike with a big spring on the front fork.
What will they re-discover next?
