Engineered for precision and built for performance, the Breakthrough Golf Technology Stability Tour Blackout Putter Shaft in .390 tip diameter redefines stability at impact. Designed specifically for putters with wider hosel bores, this shaft delivers a tour-validated, steel-like feel that enhances feedback and control on every stroke. Its ultra-stiff flex and 102-gram weight profile work in unison to minimize unwanted torque and deflection, promoting a consistently pure roll and tighter dispersion, even on off-center strikes.
Cloaked in a sleek, stealth-black matte finish with subtle gloss accents, the Blackout edition offers a distraction-free visual profile that instills confidence at address. Beyond its refined aesthetics, the .390 tip diameter ensures maximum fit versatility, making it the ideal upgrade for custom builds and modern putters with oversized tip bores. This specification, combined with a 37-inch length and .600-inch butt diameter, provides a seamless integration for a balanced, solid feel throughout the putting stroke.
Experience the fusion of elite durability and enhanced stability. The Stability Tour Blackout transforms your putter into a reliable instrument of precision, offering golfers the controlled performance and consistent responsiveness needed to conquer the most demanding greens.
