Mudguards, kickstands and bells
One bell, or two?
Both state 100 dB and both cost very little. The difference is that one publishes the bar diameters it fits and the other publishes a quantity — and in several European countries a bell is not optional.

A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these products answer different questions.
The one you can order without measuring twice. Two stated bar diameters with rubber inserts covers most of what a household has, and a 35 mm (1.38 in) dome tells you how much bar space it needs. Steel described as waterproof and rustproof is the right material for a part that lives outdoors permanently.
No amazon.com listing was found for this one. We hold references for other markets but none for the United States, so it may not be buyable here — which is the first thing to weigh against anything below.
Two bells for the price of one, in aluminum alloy with a stainless striker — a sensible material combination for something exposed to rain. It publishes no bar diameter, which on a bell is the specification that decides fit, so measure where it will actually sit and confirm with the seller.
Where the bell will actually sit, not at the stem. Many flat bars are 22.2 mm (0.87 in) at the grips and 31.8 mm (1.25 in) at the clamp, and a bell for one will not fit the other.
In several European countries, yes, and the requirement is national — Germany and the Netherlands are among those requiring one. Read the rules for where you ride.
It is a manufacturer statement measured at an unstated distance, so it is not comparable between makers in the way a lux figure is. Both of these state the same number, which tells you they are in the same class rather than which is louder.
