Super Stroke CounterCore Weight, 25g

The SuperStroke CounterCore Weight 25g is a precision back-weighting accessory designed to help golfers fine-tune the feel and balance of their putter directly from the grip end. By screwing into the Tech Port at the butt of compatible SuperStroke grips, this lightweight 25g weight shifts mass under the hands, promoting a smoother, more pendulum-like putting stroke. Ideal for golfers seeking greater stability and consistency on the greens without making permanent changes to their equipment. The kit includes the weight and a dedicated wrench for fast, tool-assisted installation.

What Is the Tech Port?

The Tech Port is the threaded access point built into the butt end of compatible SuperStroke grips. It is the interface that allows the CounterCore weight to be inserted and locked securely in place. Any SuperStroke grip featuring a Tech Port is compatible with the CounterCore weight system — simply check your grip model before purchasing.

How Back-Weighting Improves Your Putting

Adding 25g of mass under the hands via the Tech Port counterbalances the putter head, effectively lowering the swing weight of the club. This reduced clubhead awareness encourages a more pendulum-style motion, minimises unwanted wrist rotation, and helps golfers maintain a square face at impact — all contributing to greater consistency on the greens.

Choosing the Right Weight

The CounterCore system offers three weight options — 25g, 50g, and 75g. The 25g weight is the lightest option and is ideal for golfers who want a subtle change in feel and balance, or those who are new to back-weighting and prefer to start conservatively before experimenting with heavier options.
