It's the stock BB that came on the bike, so assuming a SRAM.
I'll let you know how mine turns out after service. Once the start creaking starts, it will take service to get it to stop.
My past experience with other bikes with PF BBs was that once I found a BB that didn't creak, they would last a very long time. On one bike, it was a Chris King BB that worked really well and on another bike it was a Wheels Manufacturing BB that solved the creaking.

I just scrolled down a bit on that link. Almost gagged on the price of the Ceramic Speed bb listed at the bottom. $460!!

remembering that the bikes that uses a DUB system needs a large diameter 29mm.
so you need a PF41 (with thread on cup like wheels manufacturing) for 92mm is not so easy to find,

The 20s were a 140 native. My 21 frame is 160 native. Whyyyyy. And why not mention anythhing on your site Trek. Either that or its size specific. Whyy

Only Sizes S and M are 140 mm,
The rest are 160mm native.

Not true....I have a 2021 Med AXS and has 160/160
Strange as mine doesn’t have any markings but you can see the “160” on my disc.
don’t I see a “160”on yours as well?

First ride update...
This bike RIPS. It has no business being as good as it is. The rear damping is spot on. Plenty of low speed compression and more than enough high speed (which is a good thing at 60mm). the bike just goes; it’s incredibly efficient without beating you up. With the 69 deg head angle, its SUPER fun to throw into corners..it’s just so responsive. I’m so glad they didn’t follow the SLACK BRO fad with this thing. It descends fine and comes alive in the switchbacks and tighter corners. All in all, I’m extremely impressed with it. It truly is more than the sum of its parts.

The shock surface, coils, bushings is absolutely dry. No oil at oil bath (in the back of shock).
Adding 15ml fork oil (10w, according manual), fork grease for bushings.
After service works fine, but still squeaks.

if it's a high pitched serrated-type sound, i think its just the stanchion on bushing that you're hearing.
there's a thread in the suspension section discussing burnishing these bushings (and others) because Fox/Trek f$#^%d up the tolerances. how smoothly does the strut cycle by hand?

Wanted to leave this here for logging purposes mainly, but also to check to see if anybody else had this issue...
At around mile 60 of riding(5th time out on 2021 9.8gx) my rear hub broke. I noticed i was having trouble shifting and then the pedals just started freespinning. I found the rear wheel was pretty loose so i tightened it down and then i could pedal but could not free wheel. Shop is repairing under warranty. I noticed the cassette wasn't spinning straight so assume the whole thing came apart.
