ALL IN putter shafts are a true technology standout designed for better feel, stability, and control. ALL-IN PUTTER SHAFTS ARE A TRUE TECHNOLOGY STANDOUT DESIGNED FOR BETTER FEEL, STABILITY, AND CONTROL. ACE- Aluminum Connector Enhanced Stability Technology permits the use of heavier putter heads. High Tensile modulus carbon fiber Available in 100% all carbon fiber and carbon fiber/steel combination WHAT YOU REALLY NEED TO KNOW....YOU WILL SIMPLY MAKE MORE PUTTS. Precise Feel- feel is significantly improved through the use of proprietary nano tech and nanoalloy used in the prepreg matrix. Optimum flex- Shaft stiffness is increased to minimize flexural distortion during the putting stroke for maximum accuracy and consistency. Low torque- Advanced carbon fiber material increases shaft torsional stability to lessen effect of off-center hits, for enhanced distance control
