UST Mamiya shaft
How this shaft reads against the database
2 distinct weight-and-torque points across 2 flexes are ringed. Pick one above to read its exact position.
Every iron shaft variant on record publishing both a weight and a torque, binned by density — the ringed marks are this shaft.
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.
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's on this page
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.2 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.
