If you want a bell that will grab people’s attention when you need it to, but otherwise will go unnoticed on your bike, the Knog Oi Classic could be right up your Street. In fact, once fitted to your handlebars (a simple job of just opening the sturdy plastic bracket, sliding it over the bar then tightening its bolt) you barely notice it’s there.
And as it comes in two sizes (small and large) and four finishes-black, brass, copper or silver – you can blend it so accurately to your cockpit that it becomes nigh on invisible. There are even two recesses within the bracket for cables to run under it. A simple spring-mounted hammer that hits the metal bar takes care of dinging duties, and is definitely loud enough to get you heard.
