Zefal Unisex's Bike Mirror Spin Black, 6 x 4X 1 cm

The mirror was very easy to fit. There are two expanding collars over the main bracket, to allow for bigger bars, in my case neither were needed, it fit my bars fine on just the expanding bracket. The hinges can be tightened, to make their action stiffer, and I have found them very stable in use. Being able to fold the mirror out of the way is very handy when I'm stowing the bike away.The mirror is small, but the convex surface gives a decent view behind, once properly adjusted.Update: these aren't resilient if you drop the bike and will snap off. Having said that they're still my preferred mirror.

Nice build quality, rigid plastic rather than metal keeps it light.It comes with extra shims so it should fit the standard range of handle bar inner dimensions. I have mine fitted to a hybrid with flat handlebars. The mirror is actually on the end of additional handlebar ends.The two pivot points gives you a very wide range of motion and you should be able to find a suitable position with a little experimentation. Once you have it positioned right for you then I'd mark it up with something so that you can find that positions again quickly. Useful if you have to fold the mirror to put the bike away or squeeze through somewhere. The movement is not to firm, so it is easy to adjust. But it is firm enough that it will stay where you put it on all but very rough roads. I couldn't comment on using it mountain biking off road as I've never tried that with a mirror.The mirror is on the small side but is slightly convex and gives a decent field of view. It's always a trade off between a better view and a mirror that isn't a barn door, but this suits me. I use the mirror as a backup to my hearing and shoulder checks, I don't expect it to replace those things and keep me safe.

Very easy to fit in the end of the drop bars on my bike or in the end of flat bars on my wife's flat bar road bike. Only small but gives a clear view of what is coming up behind with no vibration. My wife said she would not have a mirror on her bike because it looks daft. However this mirror is very discreet when fitted and after she started riding with it her opinion has changed, she loves it, so much she has now fitted one onto her winter bike as well. Good low cost product which works small, light and descreat when fitted. It can also be folded out of the way when you leave it parked against the wall.

Like most reviewers here, I had over many years tried various types of mirrors for my racing bike and road bike all to no avail. I was really sceptical of all of them until I came across the Zefal Spin Bar Mirror. I read through most of the peoples' experiences and came to the conclusion that it was worth trying.Simple to fit and first time out, a little fiddly to set up for my requirements but after a few miles, it became second nature to glance down at the mirror every 10 or 20 seconds if traffic behind me was busy but less often, out on the open road in the countryside. OK, some folk are critical of the fact that it is convex, so you make allowances for that and the plus side is that you get a wide view of the road behind.You still make judgements according to what you tend to hear and back it up with visual rear view vision in the mirror. It is particularly useful for being aware of these larger freight trucks when you need to be fully alert if the road narrows or there is oncoming traffic as well. Put is simply, you become more confident in your whole approach to cycling on the road which is a very good thing. At night time, you can pick out vehicles early on from their headlights some way behind.You can't put a price on safety but I would recommend this as a must for any cyclist who wants to enjoy riding around in either town or country with less fear or worries about what might be coming up behind you.I will be ordering 2 more mirrors, one for my 42 year old eldest son who has taken up the sport enthusiastically and one for my other bike.

Don't make the mistake of thinking that it will fit all handlebars despite the pictures. I bought it for my road bike that has drop handlebars but the diameter of the tube on the handlebars is too small to accept this mirror. Instead I will use it on another bike. For the price paid there are cheaper alternatives out there. If it had fitted my road bike I would have been happy. As it is, I have to continue the search. Other than that it is a compact mirror and does the job.

I always thought mirrors on bikes were a bit nerdy, but a couple of years I moved from North Yorkshire (cycling Nirvana) to north Cheshire (cycling hell) and after a few near scrapes I thought I'd give a mirror a try.WHAT A REVELATION!!I chose this mirror as I know Zefal kit to always be simple robust and well designed and this mirror did not disappoint.I big plus is it folds over the handlebars when you lock your bike to a rack so it's not going to get accidently caught up or twisted round by someone.Measurements: If fit flush into the handlebars it protrudes 98mm if orientated horizontally. If you orientate it vertically (useful for if your passing a line of standing traffic) it's height is 77mm though you obviously loose field of vision.The spindle which holds the unit onto the end of the handlebars is, as far as I can measure accurately, 14mm in diameter.It fits into the end of the handlebars and can be secured with a retaining lug that sits inside the spindle. However I ride a Carrera bike which apparently has alot of 'non-standard measurements'. The retaining lug wouldn't fit as the internal handlebar diameter is to narrow, so all I did was remove the lug and push fit the unit into the handlebars and it's perfectly secure. If you had a similar problem with your bike I guess you could glue it if you wanted to.Just to be aware; cars approaching from behind do actually appear slightly further away than they actually are, but if your serious about cycling then you'll use this mirror as what it is; a safety aid and not a replacement for eyes-on vigilance and constant situational awareness.I've never had any other mirror other than this so can't compare it to others but I highly recommend this one.

Love this mirror. Bought one a few months back, then promptly broke it after falling off my bike! Immediately ordered a replacement. The various angle options are great and the view behind you is sharp and clear.

J'ai acheté ces deux petits rétroviseurs pour ma trottinette électrique car pour tourner c'est quand même bien plus pratique avec des rétros je voulais pas de gros rétro moche j'ai trouvé celui-ci qui sont de très bonne qualité bien fini et bien plus solide que certaines sous marques chinoises on y voit très bien malgré sa petite taille et c'est des règles quasi pas en roulant en resserrant un petit peu.

Qualità ottima. Installazione semplice funzionale

Utilizo el espejo en una bici híbrida con la que hago recorridos cortos por ciudad, salidas de fin de semana a carretera y viajes de cicloturismo. He cambiado mi anterior espejo modelo Cyclop, que se rompió tras años de uso, por el Spin, que es algo más pequeño. Después de unos cientos de kilómetros, estoy absolutamente satisfecho con el cambio. Me preocupaba el tamaño, pero es el justo para ver perfectamente qué tienes detrás. En ciudad es indispensable para evitar ir girando la cabeza a cada momento, y en carretera, sobre todo cuando no hay arcén, da gran seguridad poder ver si lo que viene rugiendo por detrás es una moto, un camión o un coche.El espejo se monta sin ninguna dificultad en el extremo del manillar y se mantiene en su sitio incluso rodando sobre adoquín. Para mí, imprescindible.
