The Arundel Isabell is a compact bell designed to get attention without taking up handlebar real estate. It's Arundel's smallest bell—the kind of thing you mount and forget about until you actually need to alert someone on a crowded path or bike lane. The fixed ringer design keeps the mechanism simple and reliable. No moving parts to wear out or rattle when you're not using it.

The bell mounts with a stainless steel thumbscrew, which means you can install or remove it without digging through your toolbox. Fits 31.8mm handlebars directly, and Arundel includes shims to adapt it down to 28.6mm or 25.4mm if you're mounting it on older bars or different cockpit configurations. The mounting system keeps the bell secure without crushing the handlebar or leaving marks.

Sound quality matters with bells—there's a difference between a dull clunk and a clear ring that actually gets noticed. The Isabell produces a clear tone that carries well enough to alert other path users without being obnoxiously loud. The brass construction contributes to the sound quality. Brass has resonance properties that help the bell ring clearly rather than producing a flat, muted sound. The compact size means it doesn't interfere with brake levers, shifters, or your grip position. You can position it where your thumb naturally rests for easy access while riding. Works on road bikes, commuter setups, gravel bikes, or anywhere you need a way to signal your presence politely. Beats yelling at pedestrians or trying to squeeze past without warning.
