Simson Race bicycle bell This Simson Race bell is the classic racing bicycle bell with a modern twist. Thanks to the attachment with a rubber elastic, the bell fits on almost any handlebar (diameter of 19.2-31.8 mm). This attachment also offers a nice solution for conically shaped handlebars. The bell produces a sound of up to 85 decibels, allowing other road users to hear you coming from far away, which is useful when the speed is high.
