Reading the BBC piece on the US PGA, they said that Rory had changed his driver after round 1 as it was found to be non conforming. They also said that it's up to the player to make that known if they want. What I fail to see, is how can Rory even come close to having a non conforming driver and what is the manufacturer on that gives him one that isn't conforming?

I remember reading something before that the power he hits (a lot of players get this aswell) is that it can make the driver go non confirming through wearing the face etc . As @BubbaP says they push it to the max the manufacturers so easy for pros to make them slide into the bad zone quickly
 
Nothing sinister in my opinion...he's used that driver for some time now and with all the beating of balls they do at their speeds it's only a matter of time before the face thins and becomes non - conforming
Could be why his driving has been decidedly ropey this week...

Are you suggesting that a minuscule change to a piece of equipment has had that kind of dramatic affect on his performance? Seems unlikely to me. I know tour pros can perceive minor changes, but not to that extent. If he's that susceptible to tiny changes, he's got a big problem. Much more likely that he's just had a bad day at the office.

In any case, from the highlights I saw, it wasn't just his driving that was substandard.
 
He is not the first this has happened to.

I seem remember the only difference between the M4 and the M6 was that each M6 was tested to check it was at the maximum allowable limit.
So in effect you could have had an M4 that was as good as an M6.

I make no judgement or comment on the reason for the driver's non-conformance because I don't know anything about it apart from what is on this thread.

But I will point out that Rule 4.1a is very clear and explicit that if the playing characteristics of a conforming club change because of wear through normal use, it is still a conforming club.

Does that app,y to strokes made during the round when the club " becomes" non-conforming?
Because if the CT test shows non-conformance before the round starts then, surely, that club can't be used....?
Hence the test before the start..
 
It doesn't matter when the 'wear through normal use' occurs. Before the round, during the round, after the round. It doesn't matter what testing before the round reveals because, If the cause is wear through normal use, the club is - by definition - still conforming.
 
But this isn't the first time Rory and others have swapped out their driver because its 'become' non conforming when it was previously conforming

If it's not a breach of RoG there must be something in the tour card rules ?
 
He said fairly recently that his M2 driver (I think) was his favourite ever, but made some comment about how he still has it but it "probably wouldn't be conforming any more" due to wear on the face

As I understand it - the problem in McIlroy's and other pros case is that not all pros drivers are tested before the round, it is just random sampling. How do you then prove it was conforming at some point.

Given that the QI35 is a carbon face construction I would expect wear and tear affecting CoR not to be the case, more likely the face will end up cracking.

Rory McIlroy squeaks into PGA weekend after driver reportedly ruled non-conforming

McIlroy’s driver was reportedly ruled non-conforming on Tuesday at the PGA Championship, and three days later McIlroy had hit just 10 fairways through 36 holes.
www.nbcsports.com www.nbcsports.com

"The PGA Tour began testing drivers in 2019 to combat normal wear and tear, which pushes drivers passed the limit for spring-like effect. A player who uses a non-conforming driver in tournament play would be disqualified."

Then why would they random sample players clubs before each tournament when all those clubs have been tested before the player even uses them to make sure they are conforming?

Pretty sure they changed the rules a few years ago as they knew this was going to be a problem if a player kept his driver in the bag for long enough that eventually it would become non-conforming.
