The aerodynamic handlebar mount specifically designed for the Sigma. The shape of the mount allows the Sigma device to be positioned as centrally and closely as possible to the stem, minimizing air resistance while still being easily readable. The clamp and mounting arm are made of aluminum, providing high rigidity and stability to the entire construction. The practical hinge closure with a locking screw allows for quick and easy attachment to the handlebar. All K-Edge mounts are also compatible with carbon handlebars. The computer holder made of copolymer plastic is designed to absorb impacts or other excessive mechanical forces from outside. It protects both the computer itself and the arm of the mount from damage in the contact zone. Before more valuable parts are damaged, the mounting plate is more likely to break - and it can conveniently be replaced separately. Delivery includes: handlebar mount.
