How this shaft reads against the database
13 distinct weight-and-torque points across 17 flexes are ringed. Pick one above to read its exact position.
Weight and torque against every driver shaft
Every driver shaft variant on record publishing both a weight and a torque, binned by density — the ringed marks are this shaft.
LAUNCH AND SPIN
UST Mamiya 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 UST Mamiya 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 17 flex options: weight, torque, tip diameter and launch rating on every one; no spin rating and kick point at all.

2 of 3 parts of this shaft page are built, and we're filling in the rest.
- UST Mamiya's own specs, partly built.Taken from UST Mamiya's product page. We haven't found their full spec sheet for this shaft yet, so some figures they publish may be missing.
- Flex options, built.17 flexes, each with a published weight.
- 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.
