Sprintech Road Drop Bar Rearview Mirror, Pair, Best Bike Safety Mirror on the Market, Universal Fit for Bike Drop Bars

I purchased these mirrors after seeing one on another cyclist's bike. The design is aerodynamic and provides a view of objects immediately to the left or right. I would not buy these expecting a wide view of objects behind you. The mirrors are constructed of a tough plastic and come in a variety of colors. I was able to select a color (yellow) matching my bar tape. To be clear I am using them as pictured on drop handlebars made of an aluminum alloy. The fit is tight and this is both a benefit and a longer term issue. It makes installation tougher. I used water as a lube and that alone was not sufficient. I used a block of wood and a hammer to insert the plugs. The longer term issue is once the plugs are inserted, it is unlikely they can be removed without breaking them. Because bar tape is partially inserted into the end of the tube, I am not certain what I will need to do should I need to re-tape the bars, and this is the only downside that I have observed.I prefer this style of mirror to some of the alternatives because they are unobtrusive and in the vent of an accident, I am unlikely to be impaled by mirror parts.

These look great, and really do the job of giving you a clear view of what's behind you. I found they hold their position while you are riding, though it is easy to bump them when you're taking the bike on and off the rack, or otherwise moving it. No big deal. The rubber plugs are really a challenge to insert, but with a little soap and a lot of elbow grease (no grease!) they do eventually go in. I've used many different kinds of mirrors--helmet mirrors, handlebar mounted, etc.--and all have their strong points but for the price, weight, (un)obtrusiveness) and minimal "head movement" to view the mirrors, these can't be beat. The left side is definitely superior to the right, as others have noted, but all in all I am very pleased with the purchase.

I really like them! I bought the two pack because I hate to turn my neck while riding to see if I have cars or other riders behind me. Well these take the guess work away. I can see whats behind me on both sides

I leave this review only because they’re sold as a solution for drop handlebars.These do not adjust well on drop bara unless you have the tops/ends of yoir bars training upward. Otherwise the mirror cannot be positioned at the correct angle for a good rear view. At the most upward position they still view too low to the ground.

Pretty much perform as described and as expected. You have to adjust them prior to each ride, but once adjusted, they stay put for the duration of the ride with no problem. Great for seeing traffic and other riders in a group ride.
