Abstract
Reel devices, systems, and related methods are disclosed. The reel devices are modular and include an automatic shift assembly that shifts to provide a mechanical advantage when used to tighten a cord. For instance, the reel devices are configured to provide a first drive ratio and automatically transition to a second drive ratio in response to a torque force. The reel devices include a drive assembly and a shift assembly. The drive assembly includes a cycloidal gear.
