◤ EST. 2026 · PRECISION FITTING LAB
ForeFitter is a free golf-fitting lab with two bays. Match your ball to your swing speed, then trace your driver shaft's DNA to its best aftermarket alternatives — all on robot-tested data, all showing their work.
01 — THE BAYS
Each tool is a full fitting station on its own. Together they cover the two decisions that quietly cost golfers the most strokes: the ball you tee up and the shaft in your driver.
a.k.a. The Fitting Studio
A 4-step fitting scores 56 of 2026's balls against your swing-speed band using real slow / mid / fast robot data — then ranks them by fit, not price. Compare up to three head-to-head, filter by tier, and see every score's breakdown.
a.k.a. The Shaft Lab
Profile the shaft in your driver, see its 8-dimension DNA on a radar chart, then get ranked aftermarket alternatives by weighted nearest-neighbour match across 69 shafts and 11 makers — or work backward from a launch / spin goal.
02 — THE METHOD
Same discipline in both bays: reduce the gear to real numbers, match it to you, and always show the math. No black boxes, no upsell.
Tell us your swing-speed band or pick the gear you play. We reduce it to a real, measurable fingerprint — compression, spin, launch, bend profile.
An explainable engine scores every candidate against your profile — percentile-normalised against the whole field, weighted by what you care about.
See your best fit with a transparent breakdown, then line up the alternates head-to-head. You leave with a shortlist you understand.
03 — THE LAB
ForeFitter reads like a launch-monitor bay because that's the standard we hold the data to. Every recommendation is deterministic, documented, and free — the tools that fit you shouldn't be trying to sell you.
