- by diameter
- by the number of screws
We choose the clamp according to the type of handlebars!
Ideally, the clamp should cover the notch on the handlebars, unless the fork is longer than the notch.
If the fork is longer than the notch, we can use smaller sockets. Thanks to this, our handlebars won't crack.
Inner diameter of the socket 35 mm:
- these clamps are for both HIC and aluminum handlebars (handlebars with an outer diameter of 35 mm).
- mostly have a SHIM (spacer), which allows us to use handlebars with an outer diameter of 32 mm. We use a SHIM spacer when we want to use handlebars with an outer diameter of 32 mm (standard steel handlebars).

Inner diameter of the socket 32 mm:
- are only for standard handlebars with an outer diameter of 32 mm. (you cannot use carbon or aluminum handlebars).

The more screws we have, the stronger the clamp is, and we can tighten the handlebars better.
