How this shaft reads against the database
Flex
2 distinct weight-and-torque points across 2 flexes are ringed. Pick one above to read its exact position.
Weight and torque against every iron shaft
Every iron shaft variant on record publishing both a weight and a torque, binned by density — the ringed marks are this shaft.
LAUNCH AND SPIN
Grafalloy does not publish a launch or spin rating for this shaft. We do not infer one — a kick point is a related measurement, not the same measurement.
STIFFNESS BY SECTION
Neither Grafalloy nor our derived profile has a stiffness reading for the butt, mid and tip of this shaft. Nothing here is estimated, so there is nothing to draw.
Specifications by flex
What this record publishes. Across 2 flex options: weight, torque and tip diameter on every one; no launch rating, spin rating and kick point at all.

- Launch, spin and torque, built.Published for every flex — the figures a fitter compares shafts on.
The site is in beta and the database is still being built, so expect gaps. Know something we don't? Help us fill it in — a link to where it's published is worth more than anything else you could send.
