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 size fits 23.8 – 31.8mm bars, while the Small fits 22.2mm bars. Consult the size guide here to decide which size is right for you.

I want to use this bell, it's discreet on the handlebar and I enjoy the nice pingy sound. However, unless your city has good cycling infrastructure and people are attentive to bikes, it's simply not loud enough to break people's bubble and get them to move. I've now switched back to a classic ball-style bell.
Love my Knog oi.

I love both! Just did some riding that involved tunnels and narrow roads with clouds... headlight was powerful and got the attention on on coming traffic
