Moving Zero Torque Forward

The heart of the Tri-Hot S2S concept is moving the center of gravity (CG) far enough forward to allow the shaft to enter the head at the topline. That shift eliminates the need for forward shaft lean—a key feature in earlier Ai-ONE S2S models—and removes one of the biggest barriers to adopting a square-to-square stroke.

This change creates a neutral, upright setup that lets golfers maintain their normal grip and hand position. No forward press. No adjustment. Just a square face and a more intuitive motion through the ball.

Multi-Material Engineering

Odyssey achieved this balance through multi-material construction. By combining aluminum, steel, and more than 140 grams of tungsten, over 80% of the head’s total mass now sits directly beneath the topline. The result is stability and face control that feels natural—not mechanical.

As Odyssey’s engineers put it: “We’ve moved Zero Torque forward.”

AI-DUAL Insert and Forward Roll Design

The Ai-DUAL Insert is a dual-layer urethane face designed using Artificial Intelligence. A soft outer layer provides the familiar Odyssey feel, while a firm inner layer maintains consistent ball speed and energy transfer across the face. Working in harmony with the insert is the Forward Roll Design (FRD) Groove—deeper, more aggressive grooves with a 19° slope that help start the ball rolling forward faster, minimizing skid and distance loss.

Real-World Testing

“This design just made putting feel automatic—seriously,” said Kyle from AmateurGolf.com's Equipment Panel after testing the new #7 model. “From the first few rolls, you feel the head release naturally and the ball come off the face with instant feedback. It’s one of those setups that makes you trust your line.”

Tour-Inspired Grip and Shaft

Every Tri-Hot S2S comes with the new Pistol Plus grip, a mid-sized pistol inspired by the most popular shapes used on Tour. Crisp edges and refined tapering help golfers feel the face throughout the stroke. The grip pairs with the Black SL 120 shaft, a heavier and stiffer variant of the Stroke Lab 90, developed through player feedback for added control and stability.

Golfers who prefer a longer or counterbalanced build can opt for the Jailbird Cruiser—a 38-inch model with a heavier head, 17-inch grip, and SL 140 shaft for those who like a shoulder-driven pendulum feel.

Why It Matters

By moving the CG forward and eliminating the need for a preset hand position, Odyssey has made the square-to-square stroke more accessible than ever. The Tri-Hot S2S encourages a natural motion powered by the shoulders, producing a true roll without manipulation.

As Golf Digest notes in its exploration of zero-torque designs, “By keeping the head square longer during the stroke, you don’t have to be perfect with the line or pace.” That’s exactly what this putter achieves—a stroke that feels automatic and connected.

Availability

The Odyssey Tri-Hot S2S line opens for pre-sale October 30 at 10 AM ET / 7 AM PT and arrives in stores mid-November. Pricing begins at $549.99 for Rossie, #7, and Jailbird, and $599.99 for the Jailbird Cruiser.

For golfers who’ve wanted to roll it square-to-square without reworking their grip or setup, Odyssey’s Tri-Hot S2S may be the most natural feeling solution yet.
