Oban - Isawa Red BGT The CK designation refers to

The CK designation refers to Mitsubishi Chemical's Carbon Knit sleeve technology — a braided carbon fiber layer applied to the shaft's construction that improves torsional stability and reduces micro-vibrations

while remaining accessible enough for mid-handicap players who generate solid swing speed but want a shaft that rewards smooth

TPT constructs its shafts using an ultra-thin carbon fiber ply technology that allows significantly more carbon fiber layers to be used within the same wall thickness than conventional carbon fiber manufacturing permits — producing a shaft with distinctively low torque

producing driver carry distances that exceed what swing speed alone would predict for players with smooth
