SuperStroke's 17-inch extended putter grips are built specifically for players who position the grip against the lead forearm during the putting stroke — providing the extended surface area needed for a locked, stable armlock or belly-style setup. The extra length eliminates wrist breakdown by anchoring the top of the grip against the forearm, creating a one-lever pendulum motion from shoulder to putter face. USGA-conforming when used without anchoring the grip directly to the body. Want to see how the 17" extended grips compare to standard-length SuperStroke options?
