The Evnroll ER ZERO Z.1 Gravity Balanced Mallet Putter - Gravity Grip borrows its design from the innovative ZERO putter. Featuring the same four-point extreme weighting and powerful ball-sized “zero” alignment, the “.1” indicates the short-slant inline hosel shafting that allows the putter head to flow effortlessly down the target line. By design, the ultra-light aluminium body has a hollowed-out, ball-sized zero in the centre, which moves mass to the four corners of the head. By adding an adjustable steel weight to each corner, the Z.1 delivers extremely high MOI. But Evnroll didn’t stop there. To further enhance stability and accuracy, every Z.1 comes with the patented Gravity Grip that ties the hands to the putter face to significantly improve face angle at impact. And as with every Evnroll putter the Z.1 features our patented SweetFace Technology that virtually eliminates dispersion while producing consistent “even” ball speeds from centre and off-centre hits.
