That means if you have those cleats on your shoes, you can use them with the new Wahoo Speedplay pedals (the older non-walkable Speedplay Zero cleats will also work with the new Wahoo Speedplay pedals). NOTE: The cleats are essentially the same as the previous Speedplay Zero Aero Walkable cleats. Both are compatible with all four pedals (Standard Tension Cleats are included with Aero, Nano, and Zero Easy Tension is included with Comp). There are two cleat options: Standard Tension and Easy Tension. My Zeros tipped the scales 1 gram lighter than spec’ed weight

Aero (stainless spindle, 112 grams per pedal, single-sided entry, $279.99) – one side of the pedal has a dimpled cover that integrates with the cleat for smoother air flow.

Nano (titanium spindle, 84 grams per pedal, $449.99).

Zero (stainless spindle, 111 grams per pedal, multiple spindle length options, $229.99) – what PEZ received.

Comp (chromoly spindle, 116 grams per pedal, $149.99).

Wahoo decided to simplify things with four different models of the same familiar Speedplay “lollipop” pedal platform design:

The compact, low-profile shape of the X pedals positioned your foot closer to the spindle for more efficient power transmission and very high cornering clearance.

This lateral float was claimed to be easier on your knees.

Not needing spring tension to hold the cleat in place allowed for total free float of your foot on the pedal.

The locking mechanism for the pedal didn’t rely on spring tension which made entry easy but made unintended release virtually impossible.

No kicking, no fumbling, no looking just step down and go. And entry was relatively easy by just by stepping down into the cleat whether the pedal was right side up, upside down or anywhere else in its rotation.

The round “lollipop” platform allowed for dual-sided entry.

Compared to every other clipless pedal of the time (and still pretty much true today), the Speedplay X pedals were very different: The original Speedplay X pedal was patented by Richard Byrne in 1989 and he founded the company in 1991.
