How this shaft reads against the database
19 distinct weight-and-torque points across 21 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
Mitsubishi Chemical 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
Where this shaft is stiff and where it gives, drawn from Mitsubishi Chemical's own published butt / mid / tip ratings.
A hatched section is one with no published rating — it is drawn as unknown rather than shaded at a middle value.
Specifications by flex
What this record publishes. Across 21 flex options: weight, torque, tip diameter, launch rating, spin rating and kick point on every one.

- Mitsubishi Chemical's own specs, partly built.Taken from Mitsubishi Chemical'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.21 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.
