If you are the typical roadie, having a bell on your bike can open you up for ribbing and ridicule from your riding buddies. But the Knog Oi is not your typical bell. It’s fairly stealthy, so no one will even know you have it on board. But should you need it, maybe at a busy pedestrian intersection or passing a slower rider, the bell is at your fingertips. Once I added the Knog Oi bell, it was like magic. People got it, a biker was coming up behind them. They’d move to the side of the trail or shorten the leash on their dog (or children).
