The Odyssey S2S Tri-Hot Square 2 Square Rossie SB Putter is a breakthrough in Zero-Torque putter design, built around an all-new multi-material construction that eliminates shaft lean and positions the shaft closer to the face than any other putter in its class. The S2S Tri-Hot Rossie SB takes things one step further by incorporating a Single Bend (SB) shaft configuration, making this a heel-shafted Zero-Torque putter — a combination that gives players a familiar, traditional setup at address without sacrificing the stability and performance benefits of Zero-Torque technology. Armed with the most advanced insert Odyssey has ever produced, the Ai-DUAL dual-layer urethane design, this putter delivers consistent ball speed across the entire face, improved forward roll, and exceptional feel with every stroke. Supplied with a headcover included.
Odyssey's all-new S2S Tri-Hot construction represents a genuine breakthrough in Zero-Torque putter design. By strategically combining ultra-light aluminum, steel, and over 140 grams of tungsten, Odyssey's engineers have successfully concentrated more than 80% of the putter's total weight below the topline. This forward placement of mass allows the center of gravity (CG) and the hosel position to be moved much closer to the face than any typical Zero-Torque model — eliminating the shaft lean that has historically been the biggest barrier to Zero-Torque adoption. The result is a putter that sets up square naturally, without requiring a forward press, for a more intuitive, comfortable, and repeatable address position.
The S2S Tri-Hot Rossie SB goes one step further than the standard Rossie model by incorporating a Single Bend (SB) shaft. This configuration shifts the shaft entry point toward the heel of the putter head, resulting in a heel-shafted Zero-Torque putter — something that was previously considered impossible. The SB design delivers the familiar, traditional look at address that many golfers prefer, with conventional alignment lines and a clean sightline, while still fully preserving all of the stability and performance advantages of the S2S Tri-Hot Zero-Torque platform. Players who have been hesitant to adopt Zero-Torque technology due to the center-shaft setup of earlier models will find the Rossie SB a much more approachable entry point.
The Ai-DUAL insert is the most advanced face insert Odyssey has ever produced, engineered with the assistance of Artificial Intelligence to optimize performance across every part of the face. It uses a dual-layer urethane construction: a soft outer layer that provides exceptional feel at impact, and a firm inner layer that generates consistent ball speed whether the putt is struck in the center of the face or toward the heel and toe. The combination of these two layers also promotes enhanced forward roll across the entire face — both up and down — meaning more putts start on line and track toward the hole with ideal roll characteristics. The result is an insert that delivers the best feel, the most consistency, and the most reliable roll Odyssey has ever achieved.
The new Forward Roll Design (FRD) groove has been completely redesigned to be deeper and more aggressive than any previous Odyssey groove. With a 19° slope angle, it is engineered to work in direct conjunction with the dual-layer Ai-DUAL insert, reinforcing the forward roll effect produced by the insert both above and below the center of the face. This synergy between the groove geometry and insert construction means that even putts struck slightly high or low on the face benefit from improved roll initiation, helping the ball get up and rolling on its intended line more quickly and consistently. The FRD groove is a key reason why the S2S Tri-Hot delivers some of the most reliable, predictable roll in the putter category.
The Pistol Plus grip was developed after Odyssey surveyed the most popular grip profiles used by Tour professionals worldwide, identifying common design elements and opportunities to refine and improve upon them. The result is a mid-sized pistol-style grip with crisp, well-defined edges that allow it to sit naturally and comfortably in the hands during setup. The defined edges also significantly improve the golfer's ability to feel where the putter face is pointing at any point during the stroke, promoting better face awareness and more consistent impact alignment. Its medium sizing strikes an ideal balance between feel and stability, making it a versatile choice for a wide range of hand sizes and stroke styles.
The Black SL 120 shaft was developed with direct input from Tour players seeking a more substantial feel beneath the hands. Finished in a sleek black PVD coating, it is notably heavier and stiffer than the previous SL 90 shaft, which makes it ideally matched to the weight profile and performance characteristics of the S2S Tri-Hot Rossie SB head. The added mass and rigidity of the SL 120 contribute to a more solid, connected feel throughout the stroke, while also helping to stabilize the putter head through impact. It is an important part of the overall system that makes the Tri-Hot Rossie SB feel both premium and purposeful in the hands of serious golfers.
