Product details

As the newest addition to the popular Oi series, the Oi Prima is equipped with the new "WAVETEK" hammer technology. The redesigned hammer design ensures a more even tone and a slightly higher volume of 80 decibels. The Oi Prima fits most handlebars on the market. Simply slip it over the handlebar, tighten the hex screw briefly, and you're ready to go. A practical cable management system is integrated into the mount. Lightweight, discreet, and space-saving.

Small part, big effect: Knog has redesigned its popular Oi bell and equipped it with a new mechanism. The spring has been moved inwards, the lever has become longer, is now made of elastic, nylon-reinforced material and, when activated, hurls the metal clapper at the sound body with a vengeance. Knog promises 80 decibels. Available in various diameters and colours. Cost: 30 euros.
