Crazy is known to make some of the best performing shafts in Japan. Premium grade 40t, 50t and 80t carbon for optimal energy transfer, premium feel and impact timing. The Crazy Black Wedge shaft is made to provide stiffness and dispersion equivalent to steel in the 100-130g weight range but the kick and distance of lighter weight graphite. It is made for those power hitters and faster swingers who want more distance but do not want to sacrifice control. As a matter of a fact you may gain control over heavier steel with these shafts.
The Crazy Black Wedge shaft is 50t full length carbon available in 3 weight ranges 90g 100g and 110g. All three models are high kick for a lower launch producing more spin and control and low steel like torque of 2.0.
This is a rough guide as to flex and swing speed. (it will also depend on your tempo and transition)
Stiff 100-110 mph
The wedge shafts are 0.370" tip.
It is recommended that Crazy be installed by a professional club maker for optimal performance.
