THE TOURZONE™
Why we measured every swing on Tour so you don't have to.
WE ARE OBSESSED WITH "WHY"
At CHASSI, we don't guess. We measure. When we set out to build the world's highest-performance putters, we didn't just look at what was selling in the pro shop; we looked at what was winning on Sunday.
The "TourZone™" isn't a marketing slogan. It is the result of thousands of data points collected from the best players in the world. We analyzed head weights, swing weights, lengths, and balance points used by the top 100 players on Tour.
Why? Because success leaves clues.
THE DATA
VERIFIED TOUR DATASTOP GUESSING. START ENGINEERING.
We’ve removed the complexity of modular physics so you can focus on performance. The CHASSILATOR™ is our proprietary weight-tuning engine—a digital laboratory designed to help you architect your perfect build in real-time.
HOW TO DEPLOY:
- 01. SELECT COMPONENTS: Mix and match bodies, hosels, and face plates.
- 02. CALIBRATE: The system instantly computes Total Head Mass and TZ (TourZone™) Score.
- 03. AUDIT SWING WEIGHT: Predict your potential outcomes, ensuring your build feels as good as it looks.
- 04. LOCK YOUR BUILD: Save your unique protocol and head straight to assembly with confidence.
THE RESULT? A blueprint of professional consistency. Whether you are hunting for a 350g "Tour Standard" or an ultra-heavy 400g "Counter-Balanced" weapon, the CHASSILATOR ensures you never miss the mark.

DECODING THE TZ SCORE
You will see a TZ (TourZone™) Score attached to our setups. This is not a grade of quality. It is a calculation of Versatility.
The "TourZone™" is a specific head weight range (+/- 10 grams of Tour Standard). The TZ Score represents exactly how many unique configurations you own that hit that elite performance window.
THE CHASSILATOR™ ALGORITHM
Your TZ Score is generated by the CHASSILATOR™—our proprietary logic that calculates how many unique ways your hardware can hit the elite TourZone™ performance window.
Locked performance. You have one chance to be right. If the green speeds change, you're stuck.
Maximum Adaptability. The CHASSILATOR reveals 38+ verified ways to calibrate your head weight for any strike profile.
THE HIDDEN MECHANISM
How does the CHASSILATOR™ compute a score of 38 on a single chassis? The CHASSI TaperCore Friction System.
We engineered a tension-fit connection point held by a single set screw, hidden discreetly behind the putter face. With a dab of Loctite and a simple turn, you can swap entire Hosel/Shaft setups in seconds.
This allows you to transform a Plumber Neck Blade into a Single-Bend Mallet (AZALEA) or a Short Plumber Neck MID-Blade (FIRETHORN).
ESTABLISHING THE BASELINE
CALIBRATING FOR PACE
The TourZone™ isn't just about weight—it's about Energy Transfer. Professional green speeds vary wildly, and your TZ Score allows you to adjust your hardware to match the environment.
GREEN SPEED LOGIC:
Deploy Low Mass (<330g). A lighter head is easier to accelerate, allowing for a "pop" stroke to overcome friction without losing line control.
Deploy High Mass (>370g). A heavier head encourages a shorter, deliberate pendulum stroke, providing the stability needed on "lightning" surfaces.
THE FREEDOM TO BREAK THE RULES
We give you this data not to restrict you, but to liberate you. Once you know where the baseline is, you can make an educated decision to deviate from it.
BUILD YOUR OWN.
