If you know me, you know my long-time obsession with brains. How could I pass up a brain bell in the store? That's right, I couldn't. This bell has a pleasant chime and is fun to use. It's loud, but not too aggressive. I only award it 3 bikes because it is not passing the test of time very well. This bell has been the brains of my commuter for about 4 years now. It started sticking; meaning I can't get it to chime when I want it to. Then, it will ding randomly, sometimes embarrassingly. It dings nearly every time I go over a speed bump, but I still struggle getting the trigger to wiggle when I am trying to pass a fellow cyclist. But, that's ok. It's not too often I actually pass anyone!
