I'm a road cyclist and I feel naked and vulnerable if I can't see what's coming behind me. You all know that some drivers are oblivious to us and yet others are hostile. Better to know what's coming to be safe. This mirror is where form and function make a perfect meeting. It will adapt to any sunglass frame, is infinitely adjustable and is so light you don't notice it. I had to order a new one because I gave my old one to a vintner who admired it while I was on a trip in the Douro Valley in Portugal in May.
I ride in areas where obstructions and road conditions have me riding away from the side of the road. The mirror helps me easily see behind me so I dont have to turn my head away from the road. Clips on my sunglasses and holds its position the entire ride.
I like this rear view mirror because it goes on my glasses and not on my helmet. The only problem with this mirror for some people is that it willl not fit on their glasses. I've been using a mirror like this since 1998 - all the way across country!!
I've been using a bar-end mirror on my drops but did not like the set up. Hard to get the right view. I've been using the Bike Peddler for a few hundred miles and find it much easier to use. It does take some getting used to and it does require me to cock my head slightly to get the mirror pointing at the traffic lane behind me, but it is much easier than looking down to the bar-end mirror.
The reason you may need to cock your head with the Bike Peddler is that your shoulder would be in the way by just glancing. If you were sitting really upright on your bike all the time, this would be easier. However, if you are on a road bike for flat bar, then you shoulder partially blocks. The slight movement of your head isn't at all bad.
Lastly, don't worry about this blocking your vision or distracting you. It really doesn't do that. You get used to it after a short while. I think I'll remove the bar-end mirror now that I rarely use it.
Attach the rearview mirror to the helmetsunglasses. Twist and turn to adjust for maximum coverage and off you go. Not only that you can see how the paceline is conforming behind you but you will also see a car approaching from the back. Safety above all else!
Road biking. Helmet or eyeglass mirrors take a little while to get used to, but once you do, you'll feel hindered by the limited view of the bike mounted ones. Tried several others but kept coming back to this one for ease of adjustment and stability.
I started using a mirror as a ride leader for a local cycling group so I could keep an eye on cyclists behind me. Once I got used to it which really didn't take long, I felt I was missing a critical piece of cycling gear whenever I rode without one.
The regular version may be a bit too close to the eyes for most people since it blocks a lot of your peripheral vision. I find the extended versions works better.
The mirror slides onto the eyeglass temple pieces. Some eyeglasses, particularly the fancier cycling eyewear, have oddly shaped temple pieces that may make it difficult to mount these, so take this into consideration.
In general, I found the eyeglass mounted mirrors to be more effective than helmet mounted or bike mounted mirrors. Helmet mounted mirrors inevitably get dislodged since they are generally attached with simple adhesive. Bike mounted mirrors tend to vibrate too much for my taste, and don't have a wide enough view to get the full picture of what is behind you.
It attaches to my sunglasses and is angled for maximum and sufficient rearview. For several weeks I have used this item, the first of its kind that I have used. I have no complaints about it at all. I ride city streets with lots of motor traffic multiple times a week. No longer need I twist my neck around to see what is behind me. If you ride your bike where cars are driven, there is nothing to decide but to get this mirror.
Granted it looks a little dorky, but now that I have a mirror I don't feel complete if I am on my bike without one.
I prefer the head mounted mirror to the handle bar mounted variety, less vibration, easier to control field of view.
