Have you tried calling Titleist customer service? I was missing a zipper pull, and they sent two replacements pronto.

Cab I get a replacement bag stand for my titleist bag ?

I am looking for the straps for a teitlest players 5 stand bag..otherwise it's now a cart bag.

Nope, Titleist does not do parts as I have posted recently here on several other posts on this topic. The will do warranty returns and replace the entire bag within the first 12 months. Simple as taking it back to the authorized dealer where you got it. Some will even do an immediate exchange while they send the broken one in for inspection. If you are out of warranty, buy a "parts bag" on ebay with the same type of strap configuration. Several models have common strap types.

I bought TB20SXSF-01 a year ago, and the plastic part that keeps the stands attached keeps slipping down and then detaching. Any advice?

I had a similar issue a while back on one of my Player 4 Carbon bags. I wrapped the clamp in black electrical tape which solved the problem and blends in nicely so most people never noticed. There is a TT member who makes an aluminum replacement that screws on and will stay in place. I believe he markets them on eBay.

I need to replace the zippered panel where golf balls go, Can't find anywhere

Did you ever find a place to get the pocket flap? I need one as well.

Think Dale came up with a pretty good solution for you guys. He is a long time Titleist loyalist and makes some very valid suggestions. Might follow his advice and best of luck with eBay. Unless your bag is within the Titleist warranty bag, and you will need to take that back to where you purchased it, most likely with your receipt, eBay sounds like your best option. With respect. On spot again, Dale. See ya soon.
