Well I was tracking Excel Sports' discounted price on that DZero spider and someone must have bought the last stock. The discount wasn't enough to make me bite, so no non-buyer's remorse yet.

Rather than paying for the DZero and then (knowing my own tendencies) upgrading to better 2-bolt compatible shoes to justify having it when I already have PowerTap P2 road pedals, I stumbled across Wahoo's sale on factory reconditioned Kickrs and bought one. That, I will definitely use.
