The Sigma Aura 100 screw mount gives your bicycle light the necessary grip even in off-road use. So you can illuminate the trail brightly with your Aura 100 and rely on it even in harder passages. The joint clamp attachment holds the lamp securely on the handlebars and can be fixed easily and without tools via a thumb screw. Thanks to the included 3D mounting pads, vertical alignment is also possible on raised and/or cranked handlebars.
