I bought a couple of the new Spurcycle R50 mirrors when they first rolled out and had a nice discount. I like the appearance and functionality is pretty good. Here it is on my Cino bike:



Of course, the lens got knocked out of its base during transit, and I wasn't able to re-insert before the ride! Ah well. I did manage to get it back in once back home. I do prefer the lens of the Sprintech mirror, but the problem with that one is that it's too easily knocked out of its base: I've lost three of them that way during rides when my bike was lying on its side during a break.
