There are many different styles of scooter collar clamps on the market today, not only do these range in price but also in colours and sizes. The main purpose of the collar clamp is to hold the handlebars in place and spread the pressure that is put on the bars when doing tricks.
Typically collar clamps are available as single, double, triple or quad bolt varieties. They are also available in a choice of standard, oversized or both. It is important to get the right size clamp for your handlebars, standard size clamps are suitable for standard size bars and oversized clamps are suitable for oversized bars. Some clamps also come with a shim which allows for them to be compatible with both standard and oversized bars.
