Discover true retro ringing with the Rockbros Retro Steel Bicycle Bell. This black 15-1BBK model adds unique style to any bike while providing the practicality you expect from a bicycle bell. When creating this product, Rockbros focused on three key features: versatility, efficiency, and ease of installation. The Rockbros bicycle bell fits most bikes, thanks to two different-length straps (9.5mm and 12mm), making it ideal for handlebars with a diameter of 21 to 31.8mm. With a sound level of >75DB, the bell is loud enough to ensure your presence even in congested traffic. Rockbros allows you to easily attach and remove the bell from your handlebar using the included Allen key. It's lightweight, weighing only about 45g. Its small size makes it easy to carry and doesn't take up much space on your handlebars.
