Knog Oi Classic Bell Large
Bike bells generally look & sound a bit ugly. But why? What if they looked sexy & sounded like an angel playing a glockenspiel? A bell with a beautiful tone, but also a remarkable style and choice of materials that embodies a rider’s personality.
The Large Oi fits 23.8 to 31.8mm bars e.g. drop bar road bikes and some cruiser / commuters.
The Oi bell's shape originates from its home - the handle bar. Our design team explored hundreds of iterations in designing the style.
Then tested and prototyped different widths, depths, materials, curvature, actuators, springs and more to get to the optimum design.
Where bells usually protrude up or out, Oi doesn’t. It appears to hover around the handle bars. In one sense, it's discreet. But in another, it stands out as unrecognisable.
We tested numerous prototypes to get the perfect pitch, length of ring, and volume. With a spring-loaded actuator built into the mount, the strike of the bell is firm and fast, allowing a good balance of volume and longevity of sound. Our bell actually has several pitch tones - one core and several supportive higher tones to ensure it's unmistakable and safely heard. To compare it to a musical instrument, where some bells play a single note, Oi plays a chord. Hear it here for yourself...
What about the handle-bar cables? No worries. Built into the shape of the 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).
What about getting it on the bar. Again, not a thing. Just pop it over, give the hex screw a quick tighten up, and you're good to go. No sliding down the handlebars, no dismantling and re-assembling.
There are four styles: aluminium, brass, copper, and black.
MOUNTING THE Oi:
INSTRUCTIONAL VIDEO: HOW TO MOUNT THE Oi TO YOUR HANDLEBARS
1/ Take out the Oi and remove the hex bolt using the hex key provided.
2/ If you have the Large Oi but a 23.8, 25.4, or 26mm diameter bar you’ll need to put the appropriate spacer on your bar to make Oi sit flush. Make sure gap faces straight up. If your bar is 23.8mm, place the rubber tape provided inside the larger spacer.
3/ Manually open the mouth of the mount, and push over the handlebar if you can, fit it around your cables, there’s a space just for them.
4/ Position on a cylindrical part of the handlebar that you find comfortable, but is not curved or tapered We think close to the handle/grip, so your thumb can comfortably flick the hammer
5/ Screw in the hex bolt, firm enough to prevent any rotation, but don't overtighten (this can affect the sound quality).
