Superlative alloy construction with a universal clamp saddle to fit standard 7/8" handlebars. Beautifully made and fully adjustable 2.25"×3" platforms. Precision CNCs with a rotatable Allen-lockable upper nylon balljoint for smooth, repositionable operation. The lower joint can be positioned fore-and-aft or laterally and the upper joint swivels in all directions with a cutout so it can be nearly 90° to the stem. Position a device as low as 1.6" above handlebars for those navigational aids that don’t need to be up so high.
