A great bell for any bike
Easy to fit nice and loud.
Added a rubber shim to adapt the 22mm to a 19mm dia bar.
I bought this to replace an old Bike Bell 520 (which was out of stock). The obvious difference between the two is that the 300 is painted and a lot quiter - the specs say 5 dB quiter. Bear in mind that decibels are a logarithmic scale, a decrease by 3 dB is about a 50% reduction in volume (a reduction by 10dB is about 90%).
If it is instock, I would recommend getting the 520 instead. Definitely worth the extra 50p.
I hate those bells which you press and only get one specific ring. The btwin bell is a little like the old fashioned phones (with a dial) so when you press it you get a long, decent ring. Difficult to describe. All I can say, is go and buy one, or two, or even 3!I have a variety of colours (I bought 2 in decathlon in Spain). It really is a quality bell, and incredible value.
This bell sounds great and has a "good action" as Alan Partridge might put it. Unfortunately, its band is too small to fit on my handlebars so I had to settle for one of its siblings, which isn't as good but at least it fits!
