Z1 Center Shaft

The Z1 Center Shaft is a variant within Evnroll's Z1 mallet line, distinguished from its stablemates by hosel placement rather than head shape. According to golftipsmag.com, the putter is 100% milled from 6061 aluminum and carries Evnroll's SweetFace Technology on its hitting surface, with an adjustable pin hosel and zero torque as its stated design goal. The same source lists an MSRP of $449 USD and credits Guerin Rife as designer.

For alignment, golftipsmag.com describes two full length parallel sightlines connected to a ball sized ZERO alignment hole, a fairly literal aid for setting the putter behind the ball on line. That reporting sits alongside Evnroll's own product pages for other Z1 mallets, which describe the SweetFace groove technology in more general terms, noting closely spaced variable width channels that redirect the ball down the target line and that the maker says are built to deliver "uniform performance across the entire club face for unprecedented accuracy and zero dispersion." Those pages describe sibling Z1 releases rather than the Center Shaft specifically, so the language is instructive on the family's design philosophy without confirming spec-for-spec what shipped in this edition.

Within the Z1 line, the Center Shaft's defining trait, as reported, is the shaft position itself paired with an adjustable pin hosel, a combination aimed at golfers who want the stability of a center shafted mallet with some flexibility in setup. Everything else on record, the aluminum construction, the SweetFace milling, the zero torque claim, tracks with what Evnroll has built into other Z1 variants, making this release read as a hosel led take on a face and material formula the line already leans on.
