Which of the following lists the three types of pedal retention devices?

• A. PowerGrips, Toe Clips, and Clipless
• B. PowerGrips, Toe Clips
• C. Clipless, Toe Clips, and SPD
• D. PowerGrips, Clipless, and SPD

Answer: (A)

Pedal retention devices are about how the foot stays attached to the pedal. There are three broad approaches: toe clips (a cage with a strap around the toe), clipless systems (a shoe with a cleat that locks into the pedal), and strap-based options like PowerGrips (foot secured by a built-in strap without a separate cleat). The trio listed—PowerGrips, Toe Clips, and Clipless—covers all three categories. SPD is a specific clipless system (a brand and type of clipless pedal), not a separate category, so it isn’t a distinct third type alongside clipless. That’s why the combination including PowerGrips, Toe Clips, and Clipless is the correct grouping.
