The official blurb:

Bike bells generally look & sound a bit ugly. But why? What if they looked sexy & sounded like an angel playing a glockenspiel?

The Knog Oi bells fit on almost all cylindrical bars. The Small Oi is best for the common 22.2mm bar, and with the "spacers" that come in the pack, the Large Oi is for all bar sizes up to 31.8mm. The Oi will also work on any aero bar with a 16mm cylindrical section (usually near the stem).
