Sport or Stunt Kites consist of a sail, spars and fittings.
Most are interchangeable by size.
The spars are sized by outside diameter (i.e. 6mm or .2300) and are constructed of solid fiberglass, or carbon graphite.
You should replace spars with the same type and size spar as the original part .
All fittings (parts), are sized according to the spar diameter size.

Please refer to the diagram to locate the parts you need.
