I put this brass bell by Public on over the weekend. Imagine that, a full-suspension carbon race bike with a heavy bell like that, but let me tell you, it's worth every gram. I bet it weights close to a 1/4 pound, but that's beside the point. After riding across the Golden Gate Bridge a few times I've learned that yelling at people isn't the best thing to do, it's stressful for both sides and bad karma, not to mention all the hikers and trail users I come across in the Headlands, especially on the weekends. At least it's painted black to match.
