Replacement driver shaft?
In the event your looking at a Diamana B50 R-flex,
Wishon profiling software shows a UST Competition 75 A-Flex would be close as would a Graphite Design YS-6+ in R-Flex
older shafts but good ones. The UST might be tough to the find, but the Graphite Design should be readily available for around $50 bucks these days.
I need to know which Diamana 50 R flex shaft. There are a lot “Diamana” shafts. If you can tell me which one it would help. The only 50 gram offering we currently have in the Diamana brand is the Diamana ZF. If that’s the one, you would want to look at shafts with similar torque and trajectory profiles, along with a similar weight of course.
