Choosing the right golf equipment is often overwhelming due to the number of products available and the variations in swing dynamics. If you’re looking for shafts, two of the most popular choices are KBS TGI and Aerotech Steelfiber; but which is better?
KBS TGI shafts are better for golfers with slow or moderate swing speeds and players who prefer more lightweight shafts. Steelfiber shafts are better for players making the transition from iron to graphite and golfers with injuries because of the hybrid construction.
In this article, I’ll discuss the similarities and differences between these products, so you can make an informed decision about them. Let’s get started!
Are the KBS TGI and the Steelfiber the Same?
The following table outlines some important specifications to know before you decide which irons are best for you:
| Feature | KBS TGI | Steelfiber |
| Weight | 60-100 grams (2-3.5oz) | 75-115 grams (2.65-4.06oz) |
| Tip Diameter | 0.355 inches (8.51mm) | 0.355-0.370 inches (8.51-9.4mm) |
| Length | 36-39.5 inches (91.4-100.3cm) | 40-42 inches (101.6-106.7cm) |
| Butt Diameter | 0.600 inches (15.24mm) | 0.600 inches (15.24mm) |
The KBS TGI Graphite Iron is designed for people who want steel-like playability and performance but in a graphite shaft. The shaft improves upon the classic tour performance of the KBS Tour steel shaft and brings those features to a graphite shaft that has a smooth feel and encourages improved consistency, especially for players with a moderate swing speed.
Aerotech Steelfiber shafts are a unique blend of steel and graphite, which gives golfers a great performance and feel. These shafts are a great option for golfers who are making the change from steel iron shafts to graphite, though it still may take some practice. Additionally, Steelfiber shafts are popular amongst golfers with injuries because the hybrid construction reduces shock and vibration.
KBS TGI and Steelfiber: Which Is Better?
The right shaft for you depends on you as a golfer and your swing dynamics. If you are just making the switch from an iron shaft, I recommend Aerotech Steelfiber because the hybrid construction makes for an easier transition. I’d also recommend the Steelfiber shafts for anyone with an injury, as the hybrid construction also decreases the amount of shock and vibration that goes through the shaft upon hitting the ball.
The Steelfiber shafts are lightweight, but they aren’t as lightweight as the KBS TGI offerings. Therefore, if you are a golfer who prefers lightweight shafts and has a slow to moderate swing speed, I recommend going with the KBS TGI. A lighter weight can help golfers with slower swing speeds achieve more distance and the thoughtful KBS construction helps encourage stability and consistency.
Final Thoughts
Making the transition from iron shafts to graphite can be difficult, but it’s made easier by choosing the right graphite shaft. KBS TGI and Steelfiber are both great options, but for those currently making the transition, I recommend choosing Steelfiber. Steelfiber is also better for golfers with injuries, thanks to the hybrid technology. Golfers with slower swing speeds and those who prefer more lightweight shafts will likely prefer the KBS TGI.
