Frontline

The Cleveland Frontline line traces back to an original release that, according to read.nxtbook.com, arrived with forward weighting in the clubface designed to move mass close to the face surface while maximizing MOI, a combination the publication credited with eliminating miss-hits and widening the sweet spot. Read.nxtbook.com attributed the design to Dustin Brekke, the company's director of engineering, and reported that those first releases proved popular enough that Cleveland expanded the name into a family of models rather than a single putter. From there the line branched by neck style: read.nxtbook.com's rows show a 2.0 with a Flow Neck, an 8.0 and a 10.5 sharing a Slant Neck/Single Bend configuration, and an Elevado built on a Plumber's Neck, suggesting a line more concerned with fitting different strokes than with chasing a single silhouette.

The Frontline name resurfaces as a standalone edition alongside the numbered 4.0, and the two draw different reactions in the record. TGW.com's Rick, reviewing the Cleveland Frontline, praised the speed and distance control as easy and remarkably consistent, matching the marketing claims, and both tgw.com and golfalot.com pointed to the same 2135 alignment technology, with tgw.com specifying a sightline raised 21.35mm off the ground. TGW.com also cited 47.3 grams of tungsten mass built into the face, paired with what it called a soft feel and muted sound. The 4.0, credited by golfalot.com to Jacob Lambeth, a Research and Development Engineer at Cleveland Golf, carried the same Speed Optimised Face Technology by that outlet's account, along with a black head with red and white accents and a slightly thicker Lamkin grip. But community and editorial opinion split here: reviewers praised the 4.0's mid-range performance, alignment, and grip, while golfalot.com's own mixed verdict called it not a fit for the reviewer personally, allowing that the price point could suit a different target buyer, and other Community notes described the material as looking and feeling a little cheap with a slightly loud strike sound and head weight that felt off.

The Cero, filed under the Frontline edition, pushed the forward weighting idea further. Pluggedingolf.com described its design philosophy as moving the center of gravity forward to reduce gear effect, backed by the same 47.3 grams of tungsten split between toe and heel, finished in matte black with a triple sightline running down the top line and flange. Pluggedingolf.com called the sensation pleasant enough to want to keep hitting putts, and other Community opinion pointed to a flat lie for easy alignment and a smooth feel and sound off the face, though one note said it did not detect added speed per stroke effort compared to other high MOI putters.

The 2019 Frontline 4.0 Blade closes out the record's rows by pairing a classic blade look with the winged mallet shaping 2ndswing.com described, forged aluminum face with a groove pattern under the SOFT name, a black finish and shaft, and a Lamkin SINKFit Pistol grip with red highlights. Golfpunkhq.com listed the same tungsten forward weighting and 2135 alignment technology carried over from earlier models, alongside a £149 GBP price and 34 and 35 inch lengths. 2ndswing.com singled out the Cero specifically for its classic mallet shape and incredible forgiveness, a reminder that even within a single named release year, reviewers were weighing the line's models against one another as much as against the field.
