And while this is important in competitive situations, I don't believe this is important for casual riding or touring. even when climbing, most of that effort is spinning, until the rider stands up and starts pulling the pedals on the upstroke. So I felt compelled to find some evidence supporting clipless in pedaling efficiency over platform pedals.

Here's a video of them testing clipless and platform

It indicates that while the upstroke does play a role in clipless setups, it actually decreases your mechanical efficiency, which support the idea that the upstroke is only relevant when you're trying to beat someone up a climb or to a finishline/corner - it's not sustainable in a long ride.




What do you think? I feel like the whole argument that clipless being more efficient than platform pedals, while true in certain situations, is mere exaggerated hyperbole in most other situations. Foot retention is also important for a variety of reasons, but platform pedals can do that very well with toe clips (imo) for road riding anyway.
