Unlike other bells, which usually take up too much space, Oi bell is discreet and seems to float around the handlebars.
The Small Oi fits 22.2 mm bars, and the the Large Oi fits 23.8 to 31.8 mm bars.
Please make sure you know where on your handlebar you are going to place the bell (grips or stem) before you order. If you don’t know which sized bell you need, then check out this bell mounting video for further help.
