Frequently Asked Questions
What are the specifications of the ATOM Blue 4G?
The ATOM Blue 4G is a single-flex build: Multi-Flex (G) in the 40g class — 52 g ±1, 4.5° torque, Mid-High kick point, mid launch. Raw length 46.0" (1168 mm), parallel tip 0.337" ±0.002" (8.55 ±0.05 mm), butt 0.598" ±0.004" (15.2 ±0.1 mm).
Which other flexes and weights does the ATOM Blue come in?
Each listing is one flex and weight. The ATOM Blue family spans R, SR, S, X, XX, plus Multi-Flex (G) across the 40g, 50g, 60g, 70g classes (46–74g). Use the build switcher on this page to move between them.
Can the ATOM Blue 4G be tip-trimmed?
Tip trimming stiffens the tip section; each 0.5" step is available on the custom-build service. A per-club trim chart (driver / 3W / 5W / hybrid) is pending manufacturer confirmation — until then, do not exceed 1.0" of tip trim. Tipping is available on our custom-build service at 0.5" and 1.0".
What swing speed is the Multi-Flex (G) for?
As a guide: Under 85 mph = Regular (R); 85–95 mph = Stiff Regular (SR) or Stiff (S); 95–105 mph = Stiff (S) or Extra Stiff (X); 105+ mph = Extra Stiff (X) or Tour Extra Stiff (TX / XX). Flex is a guide, not a rule — a launch-monitor fitting with an authorized fitter confirms the right build.
Is the ATOM Blue 4G conforming to the Rules of Golf?
Yes. All ATOM shafts conform to the Rules of Golf as established by the USGA and The R&A.
