Not just another pretty face, each Marlin s clock and thermometer is made with a triple chromed billet aluminum housing and quality clock and thermometer movements. These aggressive looking mounts will add style and function to your ride. All units are waterproof, shock resistant and have glow in the dark elements (glowing elements require reasonable exposure to light for activation). If you have 4 between risers, mount two side by side or one on each side of the risers (recommended mounting 3 from bends). Available for 1 or 7/8 handlebars (clear plastic isolator used with 7/8 bars)
