I've got an STX handle that has come off the actual handle bar of my reel, it seem the pin that held the two together broke. I didn't know if any of you repair guys or someone that has had this happen to before, may have some advice on getting this fixed.

Thank you

Your wording is very confusing. Are you saying the reel handle fell off the reel? I believe that model is held on with a nut. Or I may just be confused what you are even asking.

The black handle that you put your fingers on to turn the reel, has fallen off. Sorry if that was confusing, but inside the black handle that has fallen off.. is a pin, that is suppose to connect to the handle bar. That pin has broken and I wanted to see if there was a replacement or some sort of way to repair it

Oh ok! Nope you will need to purchase a new handle for it unfortunately. If you have an spare old reels you can see it the handles off one of those would work. Or there are plenty of aftermarket options online.
