What does single release mean?

Single-release in the context of the SH-SM51 SPD Single-Release Cleat means that the cleat is designed to allow the rider to disengage or "release" their foot from the pedal by twisting the foot in one direction only. This is in contrast to dual-release cleats, which allow release by twisting the foot in either direction. Single-release cleats provide a secure connection to the pedal while still allowing the rider to quickly and easily disengage when needed by twisting the foot outward at a specific angle (in this case, a 13-degree clip-out angle). This feature is particularly useful for mountain biking and indoor cycling where quick release is important for safety and control.
