Bicycle bar ends

Horns

— additional curved accessories, installed on the ends of a bicycle's handlebars, most commonly on mountain and touring models. They are designed to change the grip and hand position while riding, which helps reduce fatigue, improve aerodynamics on flat roads, and provide a stronger support during climbs. The handlebar extensions come in various shapes and sizes, made from aluminum, carbon, or plastic, and often feature a non-slip coating for a secure grip.
