The ROCKBROS 2022-1BA is a classic brass bicycle bell designed to provide a clear and powerful alert for cyclists. Its brass construction ensures a resonant sound that reaches 100dB, making it audible enough to notify pedestrians and other riders of your presence in busy environments. Measuring 9.1 cm in length and weighing 63 g, the bell features a metallic finish and a durable nylon support. It is compatible with handlebar diameters ranging from 22.2 mm to 31.8 mm, and the included stainless steel screws ensure a secure fit. To help you get it set up, the package comes with a hexagonal wrench and two anti-slip pads of different thicknesses, allowing you to mount the bell on either the left or right side of your handlebars depending on your preference.
