Well there's this "click" noise everytime the shaft flex's on my old back up racquet, whats this mean, is it breaking or something?
the cone, glue, maybe some stuff coming loose inside the shaft... theres lots of reasons why. but it'd be a good reason to look carefully to ensure the health and longevity of your racquet, in addition to the safety of those around you.
this happened on my AT800DEF and yonex warrantied it for me. my last racket that had the click broke right off right at the shaft when i tried to smash. luckily it didn't fly and hit anyone. scared the crap outta me though...
Top of the grip splitting tends to generate that sort of noise, may be worth taking the cone and grip off and gluing the handle back together.
Would the "click" come from the frame? Then it may be the broken grommet debris. If so, just ask your stringer to take it out when restringing the racket.
it is a common problem with Yonex rackets. please check this thread: http://www.badmintoncentral.com/forums/showthread.php?t=21123
thanks for all the replies, the sound is deffinetly coming from the shaft not the head or grip though.
