Designed for riders who are seeking performance and aesthetic appeal, the Oi Prima combines sleek form with refined function to emit a beautiful tone when the hammer strikes. After years of design iterations and rigorous prototyping, the Oi Prima has emerged as a truly perfect version.

Oi Prima is completely reconstructed with the development of Knog’s WAVETEK hammer technology, which retains Knog’s unmistakable signature tone. This new hammer technology ensures a loud and consistent ring tone even after 1000's of strikes.”

Engineered for seamless integration for most bikes, the Oi Prima is offered in two sizes and a choice of Anthracite and Primer Grey, and includes an integrated cable management system that discretely routes handlebar cables, effectively solving a common problem with traditional bell mounts. The Oi Prima's installation is quick and easy; it simply slips over the bar, requiring only a hex screw tightening.
