Knog Oi Classic Bell

The bells fit on almost all cylindrical bars. The Small Oi is for the common 22.2 mm bar. The Oi will also work on any aero bar with a 16 mm cylindrical section (usually near the stem).

• Cable Management: Built into the shape of the Oi mount is a cable management system. So not only does it allow the bell to look and sound uninterrupted, it also helps gather your cables (for the organiser inside us all).
• Bike attachment: Nylon clamp with hex screw to secure bell to your bike. What about getting it on the bar? Just pop it over, give it a quick tighten up, and you're good to go. No sliding down the handlebars, no dismantling and re-assembling.
