# Shaft Information

The **stiffness** of each shaft type we offer (SOFT, STIFF & EXTRA STIFF) can be expressed in terms of the amount of deflection that occurs when a 10kg load is applied at the centre of a 1m span. This is the method that some blade manufacturers use (e.g. Braca), so it is possible to cross-reference and select the appropriate stiffness for the blade type to be fitted.
