Speedplay Zero Engagement Force
Zeros do take a bit more finesse to engage. It's more about alignment than raw force, so even at 130, once you build a bit of muscle memory in the exact foot position, you should be fine. Practice a lot.

Bottom line, it's not (mostly) a matter of force, but the Zeros have much tighter tolerances so your foot has to be just right.

FWIW: I used Zeros for track, but Light Action elsewhere...I suspect the "don't use for racing" is primarily a legal thing, but I have pulled out of the Light Actions most recently causing me to hit the ground unkindly whilst in traffic.
