Most breaks in a shaft that I have seen are down close to the hozel. This is their warranty on products. I am assuming this is the shop where you purchased the club? You could contact customer service to see what they recommend.

Have you tried to reach out to Mitsubishi Chemical? It is their shaft that failed.

Doesn’t surprise me. I had a TM m3 that cracked on the heel pad. I’d had it 6 months and it was a well known issue with that driver. TM claimed I’d slammed the club down. Thankfully my club pro was decent enough to sort me out as he knew me well enough that I don’t damage my gear.

Most companies will try to find an excuse not to pay out sadly.

I would contact the shaft manufacturer. Looks like the Mitshubushi Tensei Blue. I would reach out to them and explain.

Something irregular had to happen for it to break where its broken. Im nit sure what happened to yours, but Ive been playing golf a long time and I haven't seen many shafts just break in the middle for no reason. Titleist ppl are smart than they aren't just going to hand out free stuff. Ive have nothing but absolute class when dealing with Acushnet customer service and there are thousands of more that will say the same.

A quick eBay search for titleist tip shafts and you could replace that for $100 or less probably and it will be a way better use of your time than coming on here posting 1 time trying to say they have poor customer service.

Yep... only time i have seen a shaft break in the mid section (especially on a backswing?) is usually after some sort of impact. Slamming a club into your bag, bag falling off cart, etc. Not saying it was intentional, but certainly wasn't Titleist's fault.

Brock is right. I had a Tensei shaft on a TS2 with a clean break like that but about a foot lower. My club repair guy said the same thing. A little rough handling, or your comedian buddies pulling the strap loose on you golf cart, or your bag falling over in the garage and hitting something just right, and you get a nick on the shaft. So unless it arrived with a nick in the shaft, it is understandable that it is not a warranty issue. If you've ever regripped your own clubs you realize just how thin the wall of the shaft is from midway up is. I now use premium shafts and at their expense, I've learned to be more protective of them.

Let me add another theory. Have you had a new grip installed recently, or had the club worked on for any other reason?

I regularly work on golf clubs for customers of our club, and others outside. I do all the re-gripping as well as some club repairs/shaft installs, etc. Been doing it for years. I learned early on, the hard way, not to make the vice too tight on graphite shafts. Too much compression will crack the shaft. Your picture indicates the area where your shaft is broken is in the same area a club vise would be used. So, it may have been cracked the last time it was clamped. More often than not, you can not see a small crack made this way unless it was drastically over compressed by the vice.

When it happened to me, as it has to so many other professionals I know who work on graphite clubs (usually happens only once---you learn quickly from that mistake), I heard a very slight crack and quickly released the vice before fully engaging it. The shaft looked perfectly fine, but according to the sound I heard, internally, it was surely compromised. Luckily, it was my OWN shaft and I had a slew of others to replace it with. It may have worked for awhile, but I was not confident that it would if I sold that shaft to someone with a higher swing speed or harder transition, so it is still sitting out in my garage, years later. I could probably use it with no indication it is even broken, but sooner or later, I think it would snap at the crack when it is loaded just right.

So, I ask you, has it been in a club vise recently?
