Black Knight innovation now brings the Power Channel concept to badminton with the models of the Power Channel Series. In addition, the top models also feature the new Vibra Plate frame construction.
POWER CHANNEL - PERFORMANCE WITHOUT PENALTIES:
Would you like to have a more dynamic string bed, a larger sweet spot and better control near the frame, all without losing head speed?
Black Knight's innovative Power Channel concept delivers.
In badminton, a larger string surface means a wider and longer sweetspot and more liveliness in the strings. Yet if you enlarge the head you reduce the head speed. Thus our challenge - add more string area without enlarging the head.
The BK solution: with a Power Channel groove in the head, a racquet delivers the best of both worlds – the string surface becomes larger and more responsive, but the head size does not increase. The result: performance without penalties.
VibraPlate:
Vibra Plate Technology modifies the racquet's cross-section to stiffen the head against torsion on impact and to interrupt the transmission of shock through the frame to the handle. The result: an exceptionally solid hit - excellent for control on off-center shots, and outstanding for power hitters.
