CRG makes the best mirrors- CNC machined, perfect optics, rock stable. These are the lanesplitters, which have a folding feature so you can fold back the mirrors without changing their adjustment. Perfect for lanesplitting or storage. They are mechanically and optically perfect. They have a few TINY nicks on the front, only one got through the anodizing. I showed it for disclosure, but 2 seconds with a sharpie and you'd never find it.
They don't come with any inserts- I had my bar-end weights machined with an exact-fit grove. The inserts are cheap and readily available.
From the Revzilla webpage:

They are about $80 each- I'd like $90 for the pair shipped in the CONUS.
