THEBEAM THE BEAM – CORKY Urban Bike Mirror – Folding Rear-view Handlebar Mirror – Convex Lens with 360-degree Rotation

Easy to adjust. Shows enough that I can keep my body filling ~10-15% of the frame for my orientation and still see the whole lane behind me (and some of the next lane). Very easy to adjust while riding. Firm enough that I don’t have to adjust it over a ~20min commute with several speed bumps/ curbs. Can leave it popped out in my garage and the positioning stays where I left it for days (though popping it shut keeps the dust/smudges off). Pretty pricey but was worth it to me to not have a big, noticeable arm jutting out for someone to bend / hit.

Sitzt am Lenkerende - lässt sich klappen und drehen, ohne bei Erschütterung die Position zu verlieren. Bringt etwas mehr Sicherheit beim Radfahren. Lässt sich eingeklappt einrasten - absolut geniale Sache.

Easy to fit on handlebars, love it! Also recommend seller as they gave me a free phone holder. Thank you

This mirror is great! It is just the right size (since it's convex so it shows a larger image) and disappears when you don't need it. How cool is that to be able to just fold it away so it's not even seen! It comes with an slip on sleeve that slides right over your handgrip for instant use. It held pretty well even on rough rocky trails, but then came off when I bumped it. It also comes with an attachment that goes inside your handlebar for a secure grip. I had to cut a hole in the end of my hand grip (not a big deal, but a bit of a hassle -- you might not need to do this) to install the attachment. Anyway, love it. I got an extra to loan to others since it slips on so easily.

Muy, muy buena calidad! En verdad me gustó el producto muy útil y discreto, la entrega a tiempo y en excelente estado.
