This universal handlebar holder combines three sizes (ø 25.4 & 31.8 mm or 35 mm) and fits almost all SUPERNOVA headlights (except for the special HBM versions and the AIRSTREAM battery-powered headlight for which there are special holders). The anodized matt black bracket made of aluminium can be opened for mounting and can be mounted on the left or right side. The stem width should be a maximum of 44 mm and the bracket requires a free clamping area of 12 mm.
