The lowest stack height in triathlon
Stack height is the distance between the sole of your foot and the pedal axle. Every millimetre of it is a lever arm working against your ankle and calf on every pedal stroke — and those are exactly the muscles you need for the run.
Wahoo Speedplay pedals already run one of the lowest stacks on the market. Combined with a CarbonShell™ sole that is 3 mm thinner than conventional flat carbon, the result is the lowest stack height available in triathlon.
Direct mount, no adapter plate
The Chronos Aero sole takes a four-bolt Speedplay plate directly. No adapter, no extra material, no stacked tolerances — the cleat sits flush against the carbon.
You also get what Speedplay is known for: dual-sided entry, so you clip in without looking down out of T1, and adjustable float on both sides independently.
What's in this collection
The Chronos Bianco Speedplay edition, the direct-mount cleats for existing Chronos Aero shoes, and the Wahoo Speedplay aero pedals themselves.
