Front tuck mount
Whoa, a mount!
An actual beam mount, and therefore the devil that must be killed upon first sight, the front tuck mount is not particularly common on beam. This is ostensibly because of its risk, even though performing a risky acro element two seconds after the mount is apparently fine. It’s those first two seconds, though. They’re the most important.
In the trend toward riskier beam mounts that has grown in the current quadrennium, many of the athletes going for real acro mounts are tending toward round-off, back salto mounts rather than front salto mounts, which remain pretty rare. Of note, these front saltos were also not upgraded in 2017 when many other mounts were, though anyone performing a real mount like this gets an automatic gold star, which is worth far more than a D.
