WHAT YOU NEED TO KNOW: Odyssey’s zero-torque evolution has been methodical. First came better shapes. Then the original Tri-Hot eliminated shaft lean by pushing the CG aggressively forward.
Now the S2S Tri-Hot SB (single-bend) solves the last thing keeping some players on the sidelines: a heel-shafted configuration with conventional alignment lines and a setup that feels more traditional.

3 Cool Things 
1. The last barrier, cleared: Centre shaft and obstructed alignment. Those were the two things Odyssey’s product team kept hearing from golfers who wouldn’t make the jump to zero torque.
“We knew that zero torque’s not right for everyone,” said Jacob Davidson, Callaway’s vice-president of product strategy, “but we thought it had the opportunity with bigger imagination and innovation to expand further than it was.”
A single-bend hosel enters through the heel while staying on the same centre-shafted axis, delivering a cleaner look with standard alignment lines and a familiar setup.
Callaway staffers and club pros have been picking these up at headquarters, making strokes and asking, “Wait, is this zero torque?” after the fact. That’s the point.
2. It only works because of what came before: Moving the hosel heelward sounds simple – even if it isn’t.
“It’s such a simple change,” said Eric Stubben, Odyssey’s R&D director, “but it’s something that could really only come in an elegant way from the previous step of moving that CG forward.”
The reason it works here is that Odyssey first solved the CG problem with the original Tri-Hot, packing 120 to 140 grams of tungsten into the face to push mass as far forward as possible.
That foundation is what keeps the geometry clean and the setup natural when the shaft comes in from the heel. One step required the other.
3. Same construction, same insert: While the spud moved, everything else stayed. The Tri-Hot SB runs the same aluminium-and-tungsten build as the original, with Odyssey’s Ai Dual insert, which consists of two layers of urethane with Ai-designed RPM grooves cut at a 19-degree slope from vertical.
“The only thing that moved is the spud,” Stubben said.
The grooves are engineered for topspin and face-wide spin consistency, so heel and toe strikes stay in the same roll window as centre contact.
