Most bike bells are a protrusive embarrassment to the bike they’re attached to. Bad thing, too, since they’re actually quite useful. The Knog Oi completely changes up the bell as you know it, ditching the dome-shaped resonator for one that’s a lot more conforming to the shape of your handlebar. Oi is not one bit recognizable as a bell and hugs the handlebar to which it’s attached closely, with a well thought out recession in its ring for letting cables pass through. Available in four aluminum color variants that include brushed, brass-plated, copper-plated, and black, as well as a pricier solid titanium variant that produces a slightly deeper tone.
