The stainless steel spindle handles structural duties while a Grivory composite body keeps weight at 224 grams per pair. That's slightly lighter than the chromoly-spindled Comp but heavier than the titanium Nano. Triple sealed cartridge bearings paired with needle bearings manage the rotation. Unlike the Nano with its 180 lb rider weight limit, the Aero has no weight restriction—the stainless steel spindle accommodates any rider.

Cornering clearance measures 37 degrees, slightly less than the 39 degrees on dual-sided Speedplay models. The shaped aerodynamic underside affects the geometry, though 37 degrees still provides substantial lean angle for most road riding situations. If you're regularly scraping pedals through tight criterium corners, the dual-sided models offer marginally more clearance.

The Aero ships with Standard Tension cleats, which provide firm, locked-in engagement. Easy Tension cleats are compatible if you prefer lighter release resistance. Both cleat versions include integrated rubber surrounds that stay attached during rides and improve walkability off the bike.

Installation requires an 8mm Allen wrench for pedal mounting and a #2 Phillips screwdriver for cleat installation. Initial cleat setup benefits from patience—the adjustment range is substantial, and dialing in the optimal position takes experimentation. Once set, the hardware holds its adjustment reliably. These pedals are designed exclusively for road use.
