What Our Gearhead(R) Experts Are Saying:"The Isabell is the bell I put on bikes where I want everything to look intentional. The black finish disappears into a dark bar tape or cockpit setup in a way that brass cannot, and the stainless thumbscrew means swapping it between bikes takes about twenty seconds without hunting for a tool. The ring is clear and carries well, which is ultimately what matters most."Not every path is empty, and not every corner is clear. The Arundel Isabell gives you a clean, unobtrusive way to announce yourself before a situation becomes awkward, with a tone that carries far enough ahead to give walkers and runners a genuine heads up rather than a last-second surprise. The stainless steel thumbscrew mount installs and removes without any tools, fitting 31. 8mm bars natively and dropping down to 28. 6mm or 25. 4mm with the included shim. The black finish keeps the look of the cockpit clean and cohesive without drawing attention to itself, which is exactly what a well-chosen accessory should do.
