The Beam Corky rear-view mirror revolutionizes road cycling safety with its ingenious, ultra-discreet and foldable design. Weighing only 16 grams, it replaces your classic bar-end plug and offers panoramic vision up to 100 meters for motor vehicles and 40 meters for cyclists. Its 32 mm convex polycarbonate mirror, mounted on a 360° ball joint, allows precise and stable adjustment, even on rough terrain. Designed by the French-South Korean brand The Beam, winner of the Red Dot Award, the Corky embodies the perfect alliance between performance, safety and refined aesthetics.

Available variants

• Black — EAN 8809554460238 / Ref. BEAM-BM0016-RETR (version shown)
• White — for light handlebars and minimalist look
• Red — for a sporty touch
• Green — discreet and natural style

All variants share the same technical characteristics (weight 16 g, mirror 32 mm, compatibility with Ø 21-23 mm handlebars). Only the color of the outer ring changes, the mirror body remains black.

Technical highlights

• Featherweight 16 g: one of the lightest rear-view mirrors on the market, for completely imperceptible integration on your road bike.
• High-quality 32 mm convex mirror: made of impact-resistant polycarbonate, it offers a wide field of view with excellent depth of field.
• Exceptional range: detection of cars up to 100 m and cyclists up to 40 m behind you, to anticipate all overtaking with complete peace of mind.
• 360° rotation on ball joint: ultra-fine adjustment of the viewing angle, whatever your position (on the hoods or in the drops). The adjustment ring, equipped with an ergonomic tab, facilitates adjustment even while riding.
• Foldable and protective system: the mirror folds into its cap to protect the reflective surface during transport, storage or parking of your bike.
• Aerodynamic profile: shape designed to minimize wind resistance, thus preserving the fluidity of your rides.

Installation and compatibility

• Bar-end installation: the Corky replaces your original bar-end plug. Its adjustable expander system (similar to classic bar-end plugs) fixes securely inside the handlebar thanks to a screw tightened with the supplied 3 mm Allen key.
• Stability foot: a support pad rests against the bar tape or handlebar tape (ideal silicone thickness 3-5 mm), ensuring optimal stability without vibrations or misalignment.
• Universal compatibility: designed for road bike, gravel or fixie handlebars with an internal diameter between 21 and 23 mm.
• Ambidextrous mounting: can be installed on either the left or right side of the handlebar according to your preference. In Europe, it is recommended to place it on the left side (right-hand traffic).
• No additional tools required: everything is provided for quick and easy installation in just a few minutes.

Design and materials

• High-resistance ABS body: robust, lightweight and durable technical plastic, capable of withstanding impacts and weather.
• Polycarbonate (PC) mirror: unbreakable material offering excellent optical clarity and high scratch resistance. Unlike glass, polycarbonate absorbs vibrations better.
• Steel bolt: solid metal fixing for reliable and long-lasting tightening over time.
• Minimalist and discreet design: when folded, the Corky is barely thicker than a classic bar-end plug. The Beam logo is discreetly embossed on the inner face.

Use and safety

• Permanent vision without turning your head: keep your eyes on the road while monitoring the approach of vehicles and cyclists behind you. Ideal in a peloton, on open roads or in solo training.
• Improved active safety: detect potential hazards well in advance and adjust your trajectory accordingly. Reduces the risk of accidents related to blind spots.
• Preserved riding comfort: the negligible weight and aerodynamic profile do not affect the bike's handling or performance.
• Versatile use: road cycling outings, gravel, cyclosport, group training, commuting, long-distance cycle touring.

Usage tips

• Initial adjustment: once the Corky is installed, adjust the mirror angle by manipulating the ball joint and adjustment ring until you obtain the desired view.
• Use while riding: a simple glance is enough to monitor the approach of a vehicle or cyclist. No need to turn your head or slow down.
• Folding after use: close the cap to protect the mirror from scratches, impacts or dirt during transport or parking.
• Removal: if the tightening screw is firmly tightened, the expander may get stuck under the internal tabs. Push slightly on the screw while unscrewing to release the system.
• Maintenance: regularly clean the mirror with a soft, non-abrasive cloth to maintain optimal optical clarity.
