Sprintech Swiss-Made Convex Chrome-Plated Bike Mirror for Drop Bars – Hand-Finished, Adjustable, Reflective Surface, Durable ABS Housing (Black, Extra Large)

I’ve done more than 100K miles since I began logging in 1992, and I wish I had gotten a mirror before now. It really enhances safety. As some reviewers note, the image on these is small, but I can easily discern a car at 150 feet or more, plenty to be able to judge whether I can safely merge into a lane, which is my principal reason for wanting to see what is approaching behind. I installed both mirrors because there are circumstances in which I am in the left lane of two in a given direction and what to see what is approaching on my right. It takes about a second to look down and check the mirror and I don’t have to change my position on the bike as I need to do to look over my shoulder. I can see the mirrors in all hand positions (hoods, tops and drops). I adjusted the mirrors so that the outside of my thigh was just visible at the edge of the mirror and the horizon was centered vertically. I have needed to make minor adjustments with each ride because it’s easy to move the mirror slightly when mounting the bike or transporting it on a car rack, but this is not a difficult. I have not had a problem bumping the mirrors when mounting or dismounting the bike. Installation was easy. I used a thin film of liquid hand soap to facilitate insertion of the plug, then attached the mirror. I also like the fact that the mirrors are unobtrusive and blend into the handlebar line.
