I'm doing a 2nd review of this product because I was able to do a side-by-side comparison of the Ultralight and the Mirrcycle Bar End. This latter mirror is marketed for straight barsmountain bikes, but it works perfectly well on a drop bar. I was able to mount both mirrors on the same side of my road bike, the Ultralight being clamped about the middle of the bend in the drop bar, and the Mirrcycle plugging into the bar end. I adjusted both mirrors and rode far enough to compare the images. Both, in my opinion, are well constructed and well designed. Both are vibration-free. The advantage of the Ultralight is its wide parabolic view. While the parabolic feature means you can't see quite as far behind you the mirror gives a clear, wide, and steady picture of the road behind. The Mirrcycle does that, too, and may give a slightly longer view, but if I had to pick one for my road bike it would be the Ultralight. To be fair, there are some conditions the Mirrcycle probably does a better job and you won't go wrong buying either of them.
I own four. One for every bike. Visibility is great. Very Little vibration due to secure mount. Durable, I have tipped the bike over and landed on mirror without suffering any damage.
This is simply the best bike mirror I've found, and I've tried a lot of them. Field of view is excellent, the ball joints can be tightened, and it can be attached anywhere on a drop bar. The mirror mounts on a stalk which looks a little delicate but it doesn't vibrate in normal use and when it's mounted properly it puts the mirror far enough out so your arm doesn't obscure your view. A rating.
I've tried a bunch of rear-view mirrors and most have at least one fatal flaw, usually vibration or inadequate view. This is the only mirror I've found that does a reasonably good job of avoiding both of those problems. It has screw-clamp adjustments (more secure than friction), and a wide field of view that includes almost none of my knee. Also, the mounting system is very well thought out. I was able to find a sweet spot to mount it on my drop bars-a challenge for many designs. My one concern is the relatively small-diameter stalk that attaches the mirror to the clamp-it is vulnerable to breakage and easily knocked out of adjustment. But I can't complain too much because the stalk is the reason the mirror has a good field of view, not blocked by the leg. And while the skinny stalk looks like it would let the mirror shake when driving over rough pavement, I haven't found this to be the case. Unless you're hammering over ruts on a dirt road, this mirror will be steady.
Hard to find a decent mirror for drop bars that works and doesn't look dorky. It has good optics, no distortion and is just convex enough to give nice coverage without making everything tiny. The are several mounting options, I put mine as high on the bar as possible under the brake. I like the vertical orientation. Cars and bikes behind me are easy to see and it does not interfere with my hand. I've dropped the bike hard on the mirror a couple of times and other than some scratching on the plastic it's been fine, the mirror back, mount and stem are pretty rugged. All in all, pretty happy with it.
I use this mirror on all my road bikes because it provides a great view of the road behind. It mounts easily even on drop bars, adjusts well, and provides a large clear image. It's also reasonably durable. Many of my fellow riders ordered one when they saw how well mine worked.
I got tired of the cheap, too little mirrors that always needed adjusting or too easily broke. This one solves those problems. Has good visibility from different angles. Not quite perfect because it's mounted on the handle bar and thus there is a little bit of incovenience reaching around it on a road bike. But balanced out by always being in position and being able to be knocked around.
To be useful, the mirror must be placed below the left grip (I placed the clamp just to the inside of the grip). The view it provides is helpful, but is very small and the wide-angle surface, of course, means very little detail can be seen, if any object is seen, you must presume it's a car approaching. So, I'm glad to have it, it looks much better than a large and heavy mirror on top of the handlebar, but the view to the rear is limited and mine needs to be readjusted periodically where it swivels.
I love this mirror, the best on the market for drop handlebars. I wish it came with a longer stem and a larger mirror size. The shape of the mirror is genius.
Maybe it is because I am tall and quite a distance from the mirror but it's size limits it's usefulness. Who knows there may not be a perfect solution on a bike.
I have bar end shifters so can't try a bar end mirror.
Tried a couple of different mirrors. One gave me a perfect view of my reciprocating knee. The other made me dizzy the way it jumped around. This mirror Perfection! It's just like looking in my car's side view mirror. And it stays in place. I haven't been over rough terrain, so I can't comment about that.
I believe in bike mirrors but I do not like the helmet or glasses mounted type. This mirror works great, it is adjustable, it is clear and easy to see traffic and just is what a good mirror should be.
[...] This mirror does shake a litte, but they all do, and it is very light. Objects are closer than they appear, but the wide field of view is very helpful. I still use a helmet mirror to see what is really close, but this mirror warns me of arriving rear traffic long before I detect it in my helmet mirror. You can't have too many mirrors if you ride in traffic!
Easy to install and adjust. Mirror was used on Nashbar trekking bars as other mirrors did not work. Mirror is not as clear as the Mirrycle round mirror, possibly due to the convex shape. Overall, I have gotten use to the ok clarity as I need a mirror for my commutting needs.
