ZEFAL Spy bicycle mirror — compact convex rearview mirror with tool-free clamp (Mirror style)

The Zefal Spy Bicycle Mirror is a compact, tool-free rearview mirror that mounts almost anywhere on a bike to improve awareness. Zefal designed the Spy as a small but robust mirror that fits most bicycle frames and handlebars. Its convex, chrome-plated plastic face gives a wide field of view without adding weight, while the quick-mount system lets you attach or remove the mirror in seconds. The mirror body is unbreakable and sized to be unobtrusive yet effective for everyday riding, commuting, and recreational cycling.

How does the Spy mirror attach to different parts of my bike?

The Spy uses an adjustable clamp that accommodates tubing from 22 mm up to 66 mm in diameter, so it can be mounted on handlebars, stems, seatposts, or other round sections. No tools are required—simply open the clamp, position the mirror, and lock it in place. Its multi-position design lets you rotate and angle the mirror for the best rearward view.

• Fits tubing diameters 22 mm–66 mm for broad compatibility
• Tool-free clamp for fast on/off mounting
• Multi-position joint for precise aiming

What kind of view and durability can I expect?

The mirror face is a convex, chrome-plated plastic that resists shattering and gives an expanded field of vision so you can spot approaching traffic. At 50 mm by 40 mm, the mirror balances size and visibility—large enough to be useful yet small enough to avoid catching on obstacles. The casing and finish are built to withstand regular use and occasional knocks.

• Convex shape for wider rear visibility
• Unbreakable, chrome-plated plastic mirror face
• Compact 50×40 mm mirror surface for minimal bulk

How easy is the Spy mirror to adjust while riding?

The Spy’s joint offers smooth rotation and angle adjustment, so you can fine-tune the view with minimal effort. Because the clamp holds firmly, the mirror stays in position through bumps and light impacts. If you need a different angle later, you can quickly reposition the mirror without tools.

• Adjustable joint for precise angle control
• Secure clamp reduces vibration and slippage
• Quick repositioning off the bike when needed
