Knog Oi Classic Bell

The bell features a versatile clamp design that accommodates handlebar diameters ranging from 23.8mm to 31.8mm. This covers most standard road and mountain bike handlebars, but it is worth measuring your bar diameter if you have an oversized or non-standard setup.

The bell produces a clear, distinct, and high-pitched ping designed to cut through ambient noise on trails or city streets. While it is not an air horn, it is engineered to be audible enough to alert pedestrians and other cyclists effectively.

No, the Knog Oi Classic is a purely mechanical device. It operates via a simple spring lever action, meaning you never have to worry about charging batteries or replacing them.

The bell is designed with a low-profile, compact shape that wraps around the handlebar rather than sticking out like a traditional bell. This helps it integrate seamlessly with your existing controls, minimizing the chance of it interfering with your grip or shifters.

It is constructed from a combination of durable aluminum and plastic. This mix ensures the bell is lightweight at just 58 grams while remaining robust enough to handle regular outdoor use.
