Bar-end mirror, machined from light alloy billet and then given an anodized surface finish.
The useful area extends on an 81mm diameter, to ensure the best possible visibility. 
The mirror can be fitted in either low or high position and is compatible with most handlebars, both original and non, with an expansion assembly system (handlebar internal diameter Ø 13.5/19 mm) or with a M6 screw, included in the package.
