The bell is indeed advertised as "One Size", but this is not true! The printed package a maximum diameter of 22mm is given - far too small for the handlebars of almost all modern bikes. I had ordered the bell for my cross bike, unfortunately, is the link - just like our other two bicycles (mountain bike, city bike) - way too big.
In short measure previously Definitely, but the bell might be unsuitable for most wheels.
