SIK Flo C-Series Armlock Putter

The SIK Flo C-Series Armlock is the armlock variant of the Flo C-Series line, built for players who want the anchor point on the forearm rather than the belly. The maker's page lists a 425 g head paired with a JumboMax JMX JumboFlat 17 Putter grip, at 17 inches in length, 1.6 inches in diameter, and 130 g in weight, finished in black, silver, and grey. That combination points toward a setup meant to counterbalance the longer armlock shaft rather than rely on a heavier grip alone to do the work.

The face carries SIK's Descending Loft Technology, described on the maker's page as four flat surfaces milled into the putter face, with the stated intent of delivering consistent launch angles regardless of shaft lean at impact. That's the same core face technology found across the Flo C-Series, so what distinguishes this release from its siblings is less the face and more the fitting: 7 degrees of loft, 78 degrees of lie, full shaft offset, and 25 degrees of toe hang, all figures suited to an armlock stroke with a more upright posture and less hand rotation through impact.

Against the rest of the Flo C-Series, this Armlock version reads as the specialized fitting rather than the standard offering, aimed squarely at golfers who've already committed to anchoring against the arm and want the descending loft face concept built into that specific setup.
