I love the bright clear tone of brass bells, and I think Mirrycle makes some of the best - compact yet loud.I like the Duet model for its positive actuator action. Some people prefer the flick-type actuators, but I like this sprung lever. I can decide to sound just one or two rings, depending on how quickly I push or release the lever. And the bracket allows for a secure fit to your bars, unlike ones that use a rubber strap or o-ring, which tend to move around, though those are more easily moved from bike to bike. But at this price, just get a bell for each bike, and you’ll have a securely mounted and nice-sounding bell.
