The Callaway Shift for Summer 2026
Si Woo Kim has finalized his equipment setup for the summer of 2026. The Korean star is doubling down on Callaway technology across his entire bag. This move signals a commitment to stability and control as he chases more wins. According to GolfWRX, the details of his July 2026 WITB are now public. Fans have been waiting to see how he adjusts his driver and iron combination. The new setup looks aggressive yet precise. It reflects a player who knows exactly what he needs to win on tour.
The driver choice stands out immediately. Kim is using the Callaway Quantum Triple Diamond at 8.5 degrees. This low-spin profile suits his high-speed swing. He pairs it with a Fujikura Ventus Black 6 X shaft. For those long holes where he needs a second look, he carries a Callaway Quantum Mini driver. That club sits at 11.5 degrees with a Fujikura Ventus Black 7 X shaft. This mini-driver setup gives him a reliable option off the tee without losing too much distance.
Iron and Wedge Configuration Details
The iron setup is a hybrid mix that demands attention. Kim is not using a full set of blades or game-improvement irons. Instead, he carries Callaway X Forged irons starting from the 4-iron. From the 5-iron through the pitching wedge, he switches to Callaway Apex MB blades. This blend offers forgiveness on long irons while providing the feel and workability of a muscle back in the scoring clubs. The shafts throughout the iron set are KBS Tour V 125s. This heavy shaft choice helps him control trajectory and spin.
His wedge selection follows a similar pattern of precision. Kim uses Callaway Opus SP wedges in 52, 56, and 60-degree lofts. These clubs are designed for high spin and soft landing. He keeps the same KBS Tour V 125 shafts in these wedges to maintain a consistent feel through the bag. The ball choice is the Callaway Chrome Tour. This ball matches the rest of his equipment with a focus on short game control and driver distance. As noted by GolfWRX, this specific combination is his current choice for competition.
The putter remains a mystery to some but is clear to others. Kim is testing an Odyssey Prototype. This suggests he might be tweaking his stroke or looking for a new alignment aid. The prototype nature means it could change before the next major event. However, the rest of the bag seems locked in for the July period. The consistency in shafts and club heads shows a player who values a unified feel across his entire game.
Why This Setup Matters for His Game
This equipment choice tells a story about Si Woo Kim’s current mindset. He is prioritizing control over raw distance. The 8.5-degree driver and the Triple Diamond head indicate he wants to keep the ball down. This helps him play in the wind and on fast tracks. The mini-driver at 11.5 degrees adds versatility. It allows him to play a punch shot when necessary without switching to a 3-wood. This is a smart move for a player who faces tough conditions.
The mixed iron set is the most interesting part of this WITB. Using X Forged irons for the long irons gives him a bit more help on shots that are hard to hit. Switching to Apex MB blades for the short irons lets him shape shots around the greens. It is a classic setup for a scratch-level player. He knows how to hit a 4-iron, but he wants that extra margin of error. The KBS Tour V 125 shafts provide the stability needed for this transition. This setup balances power with precision.
The wedge selection also points to a focus on scoring. The Callaway Opus SP models are known for their spin. In the hands of a skilled player like Kim, this means he can stop the ball quickly. The 60-degree wedge is essential for high shots over bunkers. The 52 and 56-degree clubs fill the gaps for approach shots. By keeping the same shaft in his wedges, he ensures a smooth transition from his irons. This consistency is key for a player who hits the ball well.
What Fans Should Watch Next
Si Woo Kim’s performance with this new setup will be the story to watch. Fans should pay attention to his driving accuracy and iron play in upcoming tournaments. The Odyssey prototype putter might be a temporary test, so watch for any changes there. If he starts winning with this bag, other players might take notice. The Callaway Quantum series is gaining traction, and Kim’s success could push more players toward it. Keep an eye on his scores as he rolls out this July 2026 WITB.
