Racing Bike Rear View Mirror - Lightweight, Fully-Adjustable, & Vibration-Free Convex Mirror with 9 Layer Chrome Coating & Shockproof ABS Shell for 20 mm Diameter Drop Bars by Sprintech - Black

I've had these from SJS cycles before on drop bar bikes and these were the first mirrors I looked for, to see if they were still on the market, for my new bike. Very happy to see SJS selling via Amazon & that clinched it for meThey're dead easy to fit, the grips that fit inside the bars are very tough and hold firm, the ball & socket joint that attaches the mirror unit is tight & inspires great confidence against minor knocks and the worst the UK roads can judder us. The 'glass' is very clear & gives a reasurringly accurate view of upcoming traffic & it's distance away.As someone with permanent neck damage, good quality, reliable mirrors, in which you can trust the image are an essential piece of kit, not to be skimped on or hoped for the best. These are my Go-To mirrors for drop bar bikes.Also, directly in the past or 1st time via Amazon, SJS cycles service and speed of dispatch is superb.

Great product, takes a while to get best position but then is really useful. It does not replace the look over the shoulder but I use as a sneak peak to let me know what’s there. I am not sure I will use both sides but time will tell. Really easy to fit on my Triban, if it takes a really hard hit it pops out rather than snaps so pops straight back in with no damange.

Fantastic design idea. Easy to fit and then can be adjusted as ridden. Good field of view although area smaller than some. Only down side is that lenses are not glass so will scratch relatively easily. Still, given price and usefulness I’d be prepared to replace occasionally.

After reading a few of the reviews already available, I decided to go ahead and give these a go. Arrived much sooner than expected and so much better than I had anticipated from the other reviews. They are so easy to fit, and they didn't move once during a 30mile ride, even over some very bumpy areas. Highly recommended

These have proved to be an invaluable buy, though initially I thought they were a little on the expensive side. Quite hard getting the cap into the bars but shouldn't be slack anyway. The mirrors detach just leaving the end stops. They are very light and unobtrusive. The mirrors can get scratched in time, that's why I'm on my second pair! Unfortunately I had to buy the lot again as I couldn't buy the mirrors on their own. I would definitely recommend this product.

Because of my handlebars and the tilt I have them at (I am very small) I couldn't see anything other than my own knees. Might be better for people who aren't so small with t-rex arms.

Got these to replace a cheap mirror I'd been trying to use without success. These mirrors are leagues ahead from the blurry mess I was looking at before - The rubber inserts that pop into the bar-ends do seem to hold them exactly where they're positioned and the curved mirrors mean you can see everything you need. They are a great fit and are also easily popped out if you need to break the bike down to put into a car etc. If you want mirrors on your road bike, these are definitely the ones for you!

I started cycling again on my 50 year old Dawes Galaxy and found my neck just does not move like it used to as a teenager. These seemed the best of a limited bunch. They are very stiff to push on - I used some washing up liquid to lubricate as there was no way they would fit on otherwise. The mirrors work, but the image is very small up until the point the car/lorry/tractor is nearly upon you. OK if the car has its lights on. I did consider the alternatives but they have even more limitations. They are better than other options but be aware of the above issues.

Mirrors are easy to install and are very sturdy when set to view behind you. stays in place well. good safety feature...

Excellent product.

Anfänglich sah ich die Notwendigkeit eines Rückspiegels an meinem neuen Gravelbike nur darin, meine Frau, die mir im E-Rad hinterher saust, noch bei mir zu wissen.Nach Montage und Test bin ich jedoch auch im Solo-Betrieb begeistert. Man ist einfach informiert, was hinter einem los ist. Im Normalbetrieb völlig ausreichend und sehr guter, wenn naturgemäß auch verzerrter, Blick nach hinten. In sehr komplexen Situation (z. B. in der Stadt mit mehreren Spuren) sicherlich nicht mehr ausreichend.Im Fall des Falles nehme ich immer noch den Schulterblick zur Sicherheit.Montage ist stinke einfach: alte Endkappe abziehen, neue einführen und mit festen Schlägen (z. B. Gummihammer) einführen. Dann das Kugelgelenk in die neue Endkappe einsetzen. Der Spiegel sitzt fest. Klar, wenn man drankommt, ist er verstellt, was im Normalbetrieb aber nicht der Fall ist.Da bei mir das Lenkerband ins Griffinnere geht, lässt sich der Spiegel die letzten ca. 3 mm an der Dickstelle nicht mehr einführen. Entweder das Lenkerband abschneiden und einen Isolierband als Abschluss des Lenkerbandes bilden oder einfach ein Gewebeband um die Übergangsstelle wickeln.Wenn man nicht gerade einen überdimensionalen Flatterärmel hat, ist die Sicht auch nicht versperrt.Insgesamt: möchte ich nicht mehr missen. Ob tatsächlich zwei Spiegel notwendig sind, sei dahingestellt. Einer sieht aber doof aus. Beide zusammen wirken wie ein geschwungener, harmonischer Abschluss des Rennradlenkers.

Muy util

Tengo un año de uso de este espejo y desde un principio me ha sido de una gran utilidad. En mi ciudad hay muchísimos carros y el espejo me sirve para saber que pasa a mis espaldas y saber que puedo hacer, porque siempre hay coches parados en doble fila o en donde no deben estacionarse o vienen muy rápidos o muy pegados al carril donde viajo, etc. Con el espejo no tengo que estar volteando a ver tanto y puedo manejar de manera más relajada y con cierta seguridad. El espejo es convexo y tiene amplitud de visión. Está muy bien hecho, es de muy muy buena calidad y casi no se nota en la bici. Para mí, es una muy buena compra
