What Srixon Says:
Get more power where it counts—at impact. A stronger Rebound Frame design with dual flex zones delivers purer energy transfer from club face through the ball, enhancing distance on every shot. And it’s only available on new ZX Mk II Woods.

Details & Benefits:

• Rebound Frame - Most Fairway Woods have one flex zone. Rebound Frame has two. Like a spring within a spring, Rebound Frame elevates COR across the face for increased
  ball speed. And that extra ball speed leads to more distance.
• Dual Flex Zones - Most Fairway Woods have one flex zone. Rebound Frame has two. Like a spring within a spring, Rebound Frame elevates COR across the face for increased
  ball speed. And that extra ball speed leads to more distance.
• Crown Step - A stepped crown lowers the clubhead’s Center of Gravity, ultimately raising launch trajectory for higher, longer shots off the deck, with more forgiveness.
• Carbon Crown - The 3-Wood and 3+-Wood use a strong but lightweight carbon crown instead of a metal crown, maximizing COR and positioning mass low for forgiveness on
  every shot.
• Cannon Sole - A dynamic, floating weight pad moves the weight right where you want it without reducing COR—optimizing launch while also allowing space for improved face
  flex and ball speed. Especially helpful for shots struck low on the face.
