Head weight is the 11 oz (310 g) head plus the standard rear module. Every head accepts all five modules, MOD1–MOD5. Not sure about length? Most golfers fit 33–35 in; start with 34 in if your eyes sit directly over the ball.
How Zero Point Control works
A visual alignment system built into the head. Horizontal and vertical red reference lines give you one fixed checkpoint at address, on every putt. It sets up your aim; it does not change your stroke.
- AddressSet up to the ball as you normally would. No change to stance, grip or posture.
- AlignLook down at the head and find the vertical red line. When it reads as one unbroken line, your setup is aligned.
- PuttHold that setup and make your normal stroke. Nothing else to adjust.
Independently robot-tested
The Korea Institute of Golf & Sports (KIGOS) tested CYCLUX with a putting robot from 10.5 ft (3.2 m), striking the ball at the center, toe and heel of the face. Not a claim. A measured result, under identical test conditions.

Modular system
Five rear modules. Every head fits every module.
Each CYCLUX 3.1 putter ships with one standard module. The head is 11 oz (310 g); the module sets the final head weight.

Engineered around your setup
See your setup before you putt
The Zero Point Control reference lines make small changes in loft and lie easy to see at address, so you can correct your setup before the stroke, not after the miss.
Stability on off-center strikes
The cavity design places mass toward the heel and toe. That raises the head's resistance to twisting at impact, so strikes away from the center hold their line better.
Built to fit your game
Choose your length (32 to 35 in), grip (Standard or Mid) and rear module (MOD1 to MOD5). The modular design lets you change the head's weighting after you buy.
Missing straight 4-footers?
Zero Point Control gives you one fixed checkpoint at address, on every putt.

How every CYCLUX is made
Milled, not cast
Each head is CNC-machined from SUS303 stainless steel, with a milled face for a consistent impact surface.
Finished in Korea
Globally sourced components, with final engraving, assembly, adjustment, inspection, and packaging managed in Korea.
Change it later
Choose 32 to 35 in and a standard or mid grip. The rear module comes off, so you can change the head’s weighting after you buy.
Questions
Is shipping really free?
Yes. Every order ships free by express courier, worldwide, with tracking. Orders are processed within 2–3 business days. International orders may be subject to import duties and taxes. Shipping policy
What if the putter isn't right for me?
Contact us within 30 days of delivery and we'll refund your purchase under our 30-day money-back guarantee. Return shipping is paid by the customer unless the putter is defective or we sent the wrong item. Refund policy
Blade or mallet?
Blades (3.1.1, 3.1.2, 3.1.3) suit players who like a compact head and feedback from the face. Mallets (3.1.4, 3.1.5) add stability for players who want steadier distance and direction on off-center strikes.
Which length should I choose?
Most golfers fit 33–35 in. Players with a compact posture or eyes directly over the ball usually prefer 33–34 in; taller or more upright players often prefer 34–35 in. If unsure, start with 34 in.
What does the warranty cover?
1-year limited warranty from the date of purchase, covering manufacturing defects, material flaws and workmanship issues. A rear module bought separately is covered for 12 months from its own purchase date. Warranty details
