C2C In the beginning there was the SHADOW.
In 2005 BK introduced a new badminton frame technology in the first of a new series of models, the C2C Series. The C2C-SHADOW has now been joined by the C2C-Ice and the C2C-NanoFire, featuring EOS frame technology to relieve frame stress during racquet construction and create four stability zones in the racquet head for incredible control and precision.
