Flex

3 distinct weight-and-torque points across 3 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, as published

Project X rates this shaft low launch and low spin — the shading is how many of the 816 rated shafts on record share each square.

2 of 3 parts of this shaft page are built, and we're filling in the rest.

  • Project X's own specs, partly built.Taken from Project X'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.3 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.
