Simson Micro bicycle bell The Simson bicycle bell Micro 23 mm, with a rubber elastic attachment, can be mounted on almost any handlebar with a handlebar diameter of 19.2 mm to 31.8 mm without the aid of tools. The rubber elastic attachment also offers a nice solution for conically shaped handlebars. The black Simson bell has a diameter of 23 mm, which makes it very compact. Because the bell is made of copper, the bell produces a very high and long-lasting tone. The combination of the plastic frame and the universal rubber attachment gives the bell a modern and sporty look. The bell can be rotated on the frame on the bell, so that the bell can be operated at any desired angle. The bell can be mounted on both the left and right side of the handlebars.
