Review on 🚲 Pair of Oalas Black Retro Style Side Rearview Mirrors with 7/8" Handlebar Mount and 8mm Adaptor - Ideal for Mountain Bikes, BMX Bicycles, Motorcycles, Dirt Bikes, ATVs, Cruisers, and Choppers by Tony Meyer

As other reviewers have noted, they are really small. I should have paid more attention to the measurements in the description, so that's my downside. But they are also not very regulated. There isn't much room on the back of the mirrors for the ball joint to move, so they have to line up with the stems fairly closely. For example, you cannot rotate mirrors so that they are parallel to the floor. But in reality they are so small and the stems so short that I can't imagine them being useful for anything other than a toy bike. I bought these primarily for the 7/8" bar mounts and they seem to be of decent quality. I was hoping mirrors would be an added bonus but unfortunately not.
