Sprintech Road Drop Bar Rearview Bike Mirror - Safety Bicycle Mirror for Cyclists - Pair Dropbar Handlebar Mirrors for Commuting, Touring & Road Biking

I always love these mirrors and put them on all my bikes. I run a cycling club so it’s important that I see what is around me at all times when I’m riding. Wether it be other cyclist, or cars, these mirrors make it super convenient to see all that. You definitely still want to turn your head and look but sometimes it’s just nice to be able to glance down and see what’s coming at you from behind.I've had this mirror on my bike for awhile. It is very easy to install and seems to be sturdy. It does not move when riding in the street with the usual bumps. The mirror is curved so it is difficult to judge distance unless the vehicle/bike is close (at which time you might want to turn your head to take a look). You can move your handlebar slightly to scan a little. I have used helmet mirrors and this is equivalent for me. I can't imagine it will break as fast as my helmet mirror did. The down side is that it would probably not survive a spill and if you live in the city like I do it would disappear if you left your bike locked up and went into the gym for a workout (why it is a 4 of 5). Overall a good mirror, though I don't think you need one on each side unless you are actually racing and want to see that bike that is overtaking you.Ok so I picked up these after my accident last fall. I used to have bullhorns and put a mtb mirror on the end of them. It was pretty big and clear but any vibration and it was nearly useless.Now my new bike has drop bars and I couldn't use the same mirror. I ride frequently in Shanghai China so I truly need to see behind me. Frankly it doesn't matter whats behind me I just need to know if something is there. For that these are perfect, but don't expect them to give you the same view as you get from a car mirror. It's just not going to happen and I can't think of any mirrors where that will happen on a bicycle. Well at least none anyone would accept using.These are small, what you get when you look down at them is basically clear road/not clear road. Why you would need more than that I've no idea. I can see things about 40-50 yards behind me pretty well beyond that, they are just too small to make out. So if you are using these on a road where vehicles come by at a fast speed, I can see how they just wouldn't work unless you have excellent eyesight.these mount by foam rubber into the end caps. They have a ball socket that you then insert are ball on the end of the mirror. This is a press fit but not very hard to do. They stay in place by friction and I have noticed that they are fine as long as you don't go over too many washboard type roads. Smooth surfaces and they will never move on you.On the other hand I've found that getting on and off my bicycle I bump into them frequently, so every-time I start riding I need to adjust them, no biggie, just need to remember to do it.If you ride with narrow handlebars that are more narrow than you are, these are useless all you will see is your legs. If you ride with handlebars that are the proper width or larger these will work fine. The lenses are convex so you get a broader view of the road you would think for such a small mirror.Also I noticed that if I ride on the drops I'm constantly bumping them and needing to readjust them. Fortunately I don't ride on the drops so it's not really a problem.For mirrors on a drop bar bike, you could do a lot worse than these. They are a bit fiddly at times but overall I've found that they are more useful than they are a pain, which for safety gear to me is all that matters.Pros-Easy to install-lightweight-wide angle viewing for small mirrors-adjustable-blends in with bars easily-gives a good yes or no if something is behind you.-plastic won't rust-fairly inexpensivecons-easy to bump dismounting/mounting bike and also riding in the drops.-will probably wear out after adjusting too much and need new foam rubber inserts-can't see details-people with poor eyesight might not be able to use them-requires proper sized handle bars, bars too small will make them useless.Overall if you're worried about safety, get them, they are cheap enough and you'll learn to not hit them if you ride the drops a lot.My comments are only about function as a traffic monitoring safety device.Put your ego aside for a minute and give this some serious thought. Like a lot of you who are looking at this sexy mirror, I'm also a style-freak. Totally! If it does not look right, I don't buy it. The Sprintech Drop Bar Mirror is the only one in the industry that looks cool enough to pass my first filter which is, of course, style. But let's face it, a mirror is a safety device and it has to work or it's of little use. So, I'll admit to feeling "Style-Challenged" when choosing certain gear but a mirror is used by those of us who don't like hospital rooms without a view.First, the Sprintech mirror quality is truly first class. I have only praise for the high quality. The price is high but they deliver a quality product. The design is aerodynamic and sexy, the articulation is fine, it's sturdy, does not vibrate, it's compact and it's distortion free. So what's not to like? The gripe I have with this compact mirror is that, as a traffic monitor, you can't tell if a goose or Mack truck is piling up on your real wheel until it's practically on top of you. What's that song phrase? "Change is a semi with smoking wheels in your rear view mirror"? The face is small, it's convex which, on a very small surface, makes distance almost impossible to decipher. And, it's reflection-resistant dark mirror (almost black) makes it even more difficult to tell if there's any danger back there and how far away it is.......that is, until they're passing you or bumping your wheel....or you smell the burning rubber! If a vehicle has it's lights on you can see the tiny white dots in the mirror but is it in your bike lane? Is it two lanes over? Those facts are critical to making a quick decision. Next, and this is personal, but any mirror which is this small and is mounted on the end of a drop bar is automatically about 3 feet from your eye. The distance makes it more of a challenge to see what you need to know.Solution: well, sex appeal aside, I opted for a larger face mirror with less convex surface and which, granted, ain't sexy and is less aerodynamic.Bottom line: it's a matter of function vs. style The kiddish look of my current mirror selection is not a designer's delight and surely does not match the awesome looks of my new S-Works roadie. I know that. And although I did not settle for a big fat round Mirrycyle, the mirrors that really work are not exactly pretty compared to the Sprintech which, as I said at the outset, is the only mirror out there that passes my first filter which is style.Addendum two weeks later: I just purchased and tested a D&D Oberlauda UltraLight. This model is larger than the Sprintech and has all the same high qualities that I mentioned above. It's just a larger version. At this moment I have the Sprintech mounted at the only place it can be mounted...the end of the drop bar and the D&D is strapped just beneath the brake hood. The D&D can be mounted in several locations. Check U-Tube for a great video on this mirror.The reason for this addendum is to advise that the larger D&D mirror has exactly the same handicap as the smaller Sprintech. Headlights look exactly the same in each mirror. The D&D is mounted on a plastic post/rod which moves it out about 2.5 inches which helps a lot. Being wider and taller makes seeing the rear view field more easy but judging the distance of an approaching vehicle is about the same.So, in case you're wondering: "does this guy test mirrors for a living?". No, but here's my best scoop. The Blackburn "Mult-Mirror" is a clutzy looking contraption (not too juvenile-looking) but totally adjustable in every direction, quick on and off too, and it even can be folded back for storage or loading. It's bright,it's distortion-free and you can see how far back a vehicle is and it just plain works perfectly. I've popped it on and off my flat-bar city bike and my roadie and mountain bike and it's my first choice for function but last choice of these three for looking cool. But waaay more cool than some mirrors I've seen. It's not in fashion sync with lycra, bibs and team jerseys but it will save your hide if you keep a lookout for danger. Only $13.99 if you shop around.The mirrors are easy to install and look to be well made. However the mirror itself is convex and it is hard for me to see anything behind me with it. Sadly, I am sending it back.Ottimo per sicurezza senza girare la testa x vedere dietro ,prezzo mi sembra un pi caro ,ma meglio la sicurezza
