Most tracks don't like mirrors on bikes, and suggest you remove them, or at minimum tape them over for the obvious reasons. 1. glass hazard after a wreck, 2. Noob don't need to see how close the guy behind him is, he needs to concentrate on what's in FRONT of him!!
However I am looking at these, being ergal mounted, they look like they'd be pretty easy to plug in and out. Right now my regular mirrors on the bike, one has a bent stem and Ill probably end up breaking it trying to get it off, so these will probably be a lot better for me since I DO have to take them on and off.
The only drawback is when you drop the bike, the are right on the end, they are the first thing that is going to hit when it tips over. Yes Yes Iknow, keep the tires down dumbass, but stuff happens!! I Do like the fact that they are physically out further, it lets you get a better angle on your side, to see that blind spot a bit better and down the road looking wayyyyy back for blue flashing.
Ilike to keep my mirrors so I can see the lane next to me, as close up to the bike as the mirror will allow, along side me as far as it allows, and if i set the mirror correctly I can crane a bit and look down the road as well. I still ALWAYS turn my head and look when switching lanes, even when cutting up a bit, the last thing you want to do is clip someone with a tire because you didn't see them and miscalculated a duck and dive. I don't make it a habit of cutting up thru traffic but sometimes shit is happening you just have to get around for your own safety. The ribelle too, makes it sooo easy, it spoils you. After riding the bike, I get into my truck or a car and it's like gaah this ICE is so sluggish, come ON lets GO...
