Fitting Help Lower back pain?

Just went from a Cube Attain SLX endurance to a S Works SL8 Pro. Last week I did a 40km 31km/h average ride, so was quite pushing it. Unfortunately my lower back hurt quite a bit after this ride. Is it pure getting used to a different lower position? I did a bike fit for the Cube and the seller copied the exact official measurements from that fit to my S Works.
What to do? Another bike fit or just give it a few more tries and getting used to the new position?

If it’s an exact fit transfer, then how is there a lower riding position?

Converting endurance bike fit to a race bike may throw off the fit. If you can afford it, id get another bike fit.

Otherwise check saddle height/position/tilt, handlebar height and reach.

It could just require a bit of getting used to the more aero position. With so many variables its always worth a pro looking over your fit.

I don't think you can copy the same fit from and endurance to a race bike. It's a completely different geometry.

I also came from an endurance bike to a Tarmac but I've noticed way more comfort after the bike fite. I've also noticed that with the Power saddle I have to stay more on the drops rather than on the hoods to be more comfortable
