Evnroll built the Zero Z1cs to resist twisting, and a 2026 panel test agrees: only one of 37 zero-torque putters matched its stability. The robot data is less flattering, and the price asks a lot.
What's new
The Z1cs arrived in July 2025 as a center-shafted mallet, launched alongside the Z5cs hatchback and a 38-inch Tour Spec length. Evnroll mills the oversized head entirely from 6061 aluminum in the USA and finishes it in black.
Most of the mass sits at the edges: two 85 g tungsten sole weights account for up to half the head weight. Because the shaft axis runs through the center of gravity, the face has little reason to rotate, and an adjustable pin hosel lets a fitter move loft and lie two degrees either way.
How it plays
Stability carries this putter. In a 2026 panel test of 37 zero-torque models it scored 60 for stability, tied for second, and 55 for alignment, tied for eighth, which fits a head with two parallel lines and a ball-sized alignment hole to frame the ball.
Up close it is very good. A 2026 robot test gave it a short-range PuttView handicap of -8.8, which is a strong result on short putts. Distance control on longer putts lands in the middle, tied for 13th with a score of 58 on the panel.
Where it lacks
Across the whole robot test the Z1cs posted -6.5 overall and finished 12th of 26, so the short-range strength does not carry through every distance. Its overall panel mark of 70.9 put it tied for 14th of 37.
Feedback scored 48, below the class average, and looks earned only 28, so players who judge a strike by sound and sensation may find it muted. At this price, a mid-pack ranking in both tests is hard to wave away.
“Few heads twist less than this one, but at this price I wanted more speed control from distance.”- The Club Stand gear team
Reasons to buy
- Tied for second in stability among 37 zero-torque models in a 2026 expert panel test
- Tied for eighth on alignment in that same panel, helped by twin sightlines and a ball-sized hole
- Fully milled 6061 aluminum head carries two 85 g tungsten weights out in the heel and toe
Reasons to think twice
- Finished 12th of 26 in a 2026 robot test of zero-torque putters, a middling result
- Panel testers scored its feedback below the class average
- Costs premium money even by zero-torque mallet standards
