The Knog Oi Classic is a compact bicycle bell that wraps around the handlebar rather than sitting above or below it. Its most distinctive feature is that low profile shape, which keeps the bar area uncluttered and leaves the bell almost hidden in place. A spring-loaded actuator built into the mount gives a firm, fast strike.
The bell sounds several pitch tones, one core note with supportive higher tones above it, which keeps it unmistakable and easily heard. Cable management is built into the shape of the mount, so gear and brake housing can be gathered rather than pushed aside. Installation takes a single hex bolt, and the supplied hex key is the only tool needed.
