Perhaps it's cycling's Italian heritage, since you find useless mirrors only large as required by law on Ducatis and Lamborghinis. It's a no matta whatsa behinda you, gas-a-gas-a-gas!

I use the [h=1]Mirrycle MTB Bar End Mountain Bicycle Mirror[/h]https://www.amazon.com/Mirrycle-MTB-M...cmu_pg__header
but i have it pointed down and to the left, instead of up and to the left (too close to my bar ends)

i love it. it is so useful for seeing what is coming behind me on the roads, without having to constantly turn around and risk hitting a pothole or something or lose balance. honestly, i don't think i'd want to do my commute without out.

Personally, I still trust that cars are going to see me and go around, so I don't think the mirror is going to save me from being rear ended. I've always been kind of baffled by people saying they are going to dive in a ditch based on what they see in the mirror. Unless I see the big rig from Duel behind me straddling the shoulder, I'm just going expect the car to go around.

I think where it really helps me is with all the rude cyclists who pass me and don't bother to ring their bells or call out. Several times I've been about to make a left turn or dodge a pothole, only to luckily spot some a-hole passing right next to me. We both would have went down in a nasty wreck if I hadn't seen them there. For me the benefit of the mirror isn't so much safety as making my riding easier and more pleasant. Being able to see when it is clear behind me to change lanes without having to be constantly looking over my shoulder is invaluable. I suppose there is a safety component to that, because I can keep most of my attention focused on the hazards to the front of me.

Before I got my mirror I thought I'd still look over my shoulder, but the Safe Zone has such a nice field of view in it, I quickly found that I didn't need to. Now I rarely bother to look over my shoulder. I suspect part of that might be where it sits in my field of view, even without looking directly at it I think I'm subconsciously getting some information from it about what's behind me, so that a quick glance confirms that nothing is there.

Hey that Safe Zone looks like it mounts pretty well. Does it use a glass mirror by chance?

My standard procedure for being overtaken on a country road is to watch the mirror, so I can see when the car behind me applies his brakes, or comes off of his line move around me. Then and only then do I move over into the three feet or so of the lane I've been saving for myself. Without the mirror it's much harder to judge whether the car/truck/minivan-of-death, has decided to go around me or to knock me down into the ditch. The mirror is also key for this when you're driving into a headwind and you can't really hear much of anything coming from behind you.

JohnJ80

I do this too. The key is knowing when to look. I have gotten "ambushed" by cars when I don't check my mirror often enough. A prompt on when to look would be helpful.


Actually, what has my interest, is the new Garmin Varia rear facing radar. That in conjunction with a mirror would be a great combination, I think. The Varia keys you to when you should be paying attention to the mirror.

Gotta have a mirror. Even more than a helmet, gloves or that rack and baskets to make Big Red look purty.

Only been back in the saddle a week after a 30 year I-hate-us from cycling, and I miss my mirror more than any other bit of gear. Mostly because I can't turn my head anymore, due to a C2 cervical fracture.

Many moons ago I preferred a mirror on an elastic strap around my left hand. Easy to adjust the angle just by clenching or turning my hand slightly. Looks like only some ATV type sporting goods dealers carry those now.

Leisesturm

And Amazon... I gave these a try last year after hearing about them here. I went all in and got two. I didn't find them useful. Perhaps if I did the Lowrider thing and rocked ape hanger handlebars. I kept them because I might just build a recumbent someday, but if you are interested... I'd let them go for the postage which shouldn't be much, they're pretty light.

Two mirrors for me. I use a Take-a-Look mounted on my helmet and a STI mounted Mirrycle. Really like this set-up.

Shahmatt

I have the Take-A-Look mirror.

Consider a situation where there are vehicles all around and the road conditions aren't great. There is no time to look behind to check on approaching vehicles. In order to maneuver you would need to slow down and stop, look behind proper, and then start moving again.

Mirrors help a lot here. With a mirror you could see what's behind you properly with more time. You would note speed and positioning relative to yours, and this information would enable you to maneuver in the way you want without having to stop and check.

Mirrors are enabling!

Not really.

I have trouble with the helmet-mounted mirrors, partly because they're so tiny, and partly because I can't position them in a way that doesn't seem to strain my eyeballs every time I want a quick glance. I tried a cheap handlebar mirror, but it was bouncing like crazy. Any recommendations for a stable, generous-sized, reasonably-priced handlebar mirror? I'd be attaching it to a hybrid.

Even with a mirror, I'll still make a big show of turning my head. I think the extra motion helps get drivers' attention, plus I like making eye contact when possible.

Looking over one's shoulder before maneuvering is a must. It's called "a lifesaver" in motorcycling. In a car you could damage a car, on a two wheeled vehicle you can get seriously injured. Always look over one's shoulder just in case - checking blind spots. Mirror just makes it possible to do just one look over a shoulder - once you see in the mirror it is clear. Instead of looking many times until it is clear (without a mirror). But having a mirror should never exclude checking over one's shoulder before turning. It can be a costly one second "saved".

Jim from Boston

Same here (with my Take-a-Look), but this morning I realized one situation where I always do a shoulder check. When I'm at the curb at a stoplight, I do a left over-the-shoulder look to make sure the car on my left won't right hook me.

A valuable adage I learned on BF is that you can only reliably predict the direction of a car, especially a stopped one, by the direction of the front wheels, which I can't see when next to me.

I have one of these on my hybrid - the Mountain version:
https://www.mirrycle.com/mirrycle_mirrors.php

The parts are tightly threaded - meaning you would have to work hard to screw the parts together and secure it onto your bike. But the other side of that coin is that it's stable. Once you have it set to the angle you want, it will stay there until you fold it away. It gives me a good rear view of the lane to my left as well as anything coming up behind me. My only complaint is that when I touch it with my sweaty hands the moisture stays there, so I try not to touch the mirror surface directly when I adjust it.

JohnJ80

The best mirror with respect to bouncing that I have found is the Bike Eye. Handlebars are going to be bouncier than the frame.

I've been considering a helmet mounted mirror. My motto is better alive than cool, and explains why my cycling gloves are day glo yellow and not a "cool" color.

Leisesturm

With the possible exception of Trekking Bars, there are very few bike components that are inherently 'uncool'. It's in cyclists minds that such and such component or item of safety gear is "Fred". Most non-cyclists think helmet mirrors are kind of funky and ... 'sool'. I get many positive comments on mine. You are on your own with the day-glo gloves. No experience there.

Leisesturm

Absolutely. Quoted in entirety for emphasis. This should really be the last word. Is there another field of human endeavor where so much misinformation is promulgated by the ignorant as sage wisdom and competes head to head with reality in an ongoing existential stalemate? It would simply be head scratching if it weren't for the fact that cyclists are out there dying for their ignorance, and refusal to adopt safer practices in light of new information.

JohnJ80

Day-Glo gloves ensure that certain hand gestures emphasizing usage of certain fingers are seen better in low light conditions.

I think the main controversy on mirror threads such as this one is that many subscribers post that shoulder checks eliminate mirrors, not the mirrors eliminate shoulder checks. Because mirrors can be periodically viewed, one often knows what’s behind for quite a distance. Of course if uncertain about what’s immediately behind, a shoulder check is useful. But I think a shoulder check can be limited by how far you can twist, and how long you want to linger scanning the rearward view.

The hazard of shoulder checks is that you need to turn your head and eyes away from the line of travel. Not infrequently I am going downhill pretty fast, on a pothole-strewn-road, and I can nearly simultaneously view frontwards and rearwards with a rearview mirror.

My argument for use of a mirror is Jim’s Law of the Road, ”No matter how well-paved and lightly traveled is the Road, a vehicle is likely to pass you on the left as you encounter an obstacle on the right.”

Bike Gremlin

I agree - mirror makes it easier to scan the situation behind. Which leaves you with one shoulder check - just before making a turn. Just in case. Just if someone, somehow, manages to get to your blind spot, in spite of using mirrors. It is a wise thing to do whether driving a car, motorcycle, or a bicycle (with a mirror).

If you haven't got the time for a shoulder check, you're going too fast for the traffic conditions.

I think it was Lincoln who said one should keep silent and let others think they are a decent, stand-up kind of guy than to speak out and kill the notion...

Jim from Boston

So true. Just this morning I posted above:

JohnJ80

I grew up in Chicago in the Land of Lincoln. The gestures are part of the rating system that drivers use to give "feedback" to one another. Notice that the gesturing insures silence.

I have on the odd occasion in my past life as a frequent flyer Interstate commuter been guilty of checking my wing mirror and then, seeing it all clear, launching the Turbo Passat in a high G lateral drift right into the idiot who has been loafing along to my immediate left without passing me! Every time this has happened, some latent instinct to do an actual visual check has saved our bacon's as I then have to haul her back into my lane, scaring both myself and the other driver badly, but leaving our collision deductibles unspent.

I will complete lane changes on a bicycle with only my mirrors word for it that the situation is clear, but on a bike one is far more exposed to auditory, olfactory and peripheral visual cues that can corroborate (or refute) the mirrors verdict. It cannot be recommended as a best practice, however.
