  • 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.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.
