Incredibell Brass Duet Bell

The Incredibell Brass Duet is designed to fit standard bicycle handlebars with a clamp diameter of 22.2 millimeters. This is the most common size for standard commuter and hybrid bikes, but it is worth measuring your bar diameter if you have an oversized or non-standard setup.

This is a mechanical bell, meaning it relies on a spring-loaded lever that you flick with your thumb. The internal hammer strikes the brass dome twice in quick succession, producing the classic two-tone sound.

Yes, because it is made of solid brass, the bell will naturally develop a patina over time when exposed to the elements. Many riders prefer this weathered look, but you can easily polish it with a standard brass cleaner if you want to maintain a bright, shiny finish.

The resonant tone of the solid brass construction is designed to cut through ambient city noise better than plastic or aluminum alternatives. While it is effective for alerting pedestrians and other cyclists on shared paths, it may not be as piercing as a high-decibel electronic horn in heavy traffic.

Yes, you will need a standard screwdriver to tighten the mounting clamp onto your handlebars. The installation is straightforward and typically takes less than two minutes.
