Knog Oi Classic Bell Large

The Large version of the Knog Oi is designed to fit handlebars with a diameter between 23.8mm and 31.8mm. This covers most standard road and mountain bike handlebars, but it is best to measure your bar diameter at the mounting point before purchasing.

The Knog Oi produces a distinct, clear 'ding' sound that is crisp and audible without being jarring. Because of its unique shape and spring-loaded striker, the sound is slightly more refined and less resonant than a classic, large-dome bicycle bell.

Installation is straightforward and requires only a standard hex key. You simply wrap the clamp around your handlebar, tighten the screw, and the bell sits flush against the bar, keeping your cockpit clean and uncluttered.

The bell's low-profile, wrap-around design is specifically engineered to minimize handlebar clutter. While it fits most setups, its slim footprint usually allows it to sit neatly alongside your existing controls without causing interference.

Yes, the construction combines aluminum and plastic to balance weight and durability. It is built to withstand regular use in various weather conditions, though like any bell, it should be kept clean to ensure the spring lever mechanism continues to operate smoothly.
