They come up with some amazing ideas, don't they?
(We'll graciously overlook the L - shaped cranks from the 1980s.)
My own pair of Sidis (which features TWO of these wonderful adjustments!) has a crazy worm gear tensioner in the sole. I've worked it one way and the other and as far as I can tell it's completely useless. I think the idea was to fool idiot Americans into thinking it was functional so we'd fork over the extra $50 or whatever.
My shoes were a gift to me, thrown into a package which included a beautiful royal blue Pinarello Vuelta with an accompanying extra Chorus cluster and chain, all for the astonishingly absurd amount of $600. As good as the shoes felt/worked right away and have ever since I'd say I robbed Dick Fisher blind, except that the price was his idea.
Thank you again, sir.
Oh, right. The review.
Oh, but it's "fine Corinthian plastic!"
Whaddya gonna do, spend $300 on a new shoe? Pay the man and let's get out of here.
