OnOff Kuro Irons (2026)
XCBT (Xtreme Carbon Balance Technology) is now in its third generation. For over four years, ONOFF has been developing a solution that allows the weight and balance of a golf club to be tailored to personal goals and individual playing preferences. Even a difference of just one gram in a driver can make a significant difference during fitting.
The irons are based on a hollow structure and an S20C Spring Roll face, which is 5% thinner (2.2 mm) than its predecessor.
Elegant design with significantly improved feel for even better feedback. The club face has been enlarged by 6% to 16% depending on the point of impact. XCBT technology optimally adjusts the moment of inertia and center of gravity to achieve a better feel and performance depending on the swing.
Laser engraving can be found on all ONOFF clubs. The letters O N O F F are hidden on each clubface. In addition to its striking appearance, which is a trademark feature, this laser engraving influences the roughness of the clubface to create consistent spin at the moment of impact.
