CRG Mirror users - Is it me or do you notice that CRG mirrors are awful at gauging distances?  It makes objects appear a lot further than they actually are.  I notice that when I turn back to look at other rider and compare to the mirror, the disparity is just way too much.

I use those bar-end mirrors to see if anything is behind me in adjacent lanes.  BUT I always turn around to see if the lane is clear before I change lane.  I do the same when driving, too.  Just a safety habit I picked from Driver's Ed...

Mirrors are only a piece of the puzzle. I head check as well before switching lanes as added insurance.

I have the same issue with my CRG Blindsight.  It has a really wide field of view.  I wonder if it has something to do with the convex shape of the mirror itself.

most mirrors do that, as you can see in car mirrors where they say 'objects in mirror are closer than they appear'. Probably done that way so you have a wider view of what is around you.

I also have the CRG mirrors. I use them to keep an eye out on whats behind me, but I still peek over to make sure lanes are safe before moving

They do take some getting used to, but as previously stated, I always do a Head-check in addition.

Yep, head check is a must for sure.

In group rides, I notice that rider behind me looks very far if just go by the mirror only.  When do head-check, the rider is really right behind me.   Got to be careful.  Stock mirrors are not that bad for that (although any mirror, head-check is a must). 

I am wondering which bar end mirror is better?

It has everything to do with the shape.

yep... you get used to them.  Enough time with them and checking over your shoulder and you learn where the car is. 

Only thing that sucks is, you see a car back there... can't tell if it is a police car or not which you can with non-convex mirrors.  WOuldn't give up convex mirrors for this reason though.  They let you see WAY too much behind you.

Yep yep.  CRGs are convex - giving you a wider field of view with the trade off that there is distortion.  One effect that distortion has is tricking your brain when it comes to perceived distance vs actual distance.  Flat class mirrors give a more accurate sense of distance , but you loose on that wide angle view.

Thsoe stickers on car mirrors is mostly due to the size of a car/ your distance from the mirror.  Notice it's only on the passenger side - the furthest mirror from you.  As a result of that distance you brain thinks the objet  in the mirror is 3,4,5 feet further back than it actually is.

Yea, not being able to distinguish what type of car ( Police ) it is can be a little frustrating.  Wasn't an issue with my old Rizomas.  But the CRG's (or CRG in my case) look much, much better on the bike.  Nothing like sacrificing safety for looks.  I do have a better since that something is behind me with the CRG though.  The mirror on the end of my bar has a better angle for line of sight.  With my Rizomas, I would have to adjust my arms and shoulders to get a good look.  As far as lane changes, no mirror can ever take the place of turning to look.

I didn't realize how truly horrible the crg mirrors are in this regard until I broke one of the mirrors. I went to an autoglass place and they were kind enough to replace the mirror right away for me for about $5. The difference was incredible with the autoglass mirror being quite accurate while the remaining crg mirror is now virtually useless to me. I'm going to go have it replaced as well.

I think that is all personal preference.  I bought the CRGs specifically because they were convex.  Well, that, and because they look awesome on the bike.  With the stock mirrors I had a great, undistorted view of my shoulders.  With the CRGs I can see behind and to the sides of the bike.  I feel that I have much better situational awareness.  I'm not as concerned about being able to identify who, specifically is behind me.

I was just about to order a pair of the CRG lane splitters when I came across this thread. Is there another company making   end mirrors that anyone would recommend? From reading DMF, everyone seems to have the "elbow view" with the stock mirrors.

Any suggestions other than CRG?
