Black aluminium mirrors with blued lenses to reduce glare. The lens intself is 10cm wide and 5cm high. Good firm hold once placed in position around a 360 degree axis. Can be mounted above or below the bar and turned in or out to sit above your hands or extending outward from the end of the bar.
Fits in the end of any standard 7/8" or 22mm hollow bar with an internal opening of 16-19mm. Expanding section to hold them tight is rubber so can actually be shaved down for smaller bar openings. (I have done this myself on a set of fat MX bars)
Listing is for two mirrors which can be swapped to either side, so if you just want to run one, sell the other to a mate for beer money.
Nice black anodised finish and shape looks more modern than the standard round ones.
