Need recommendation for rack for paniers
I bought Ortlieb Gravel Pack Pannier set. I can not find a rear rack for it the clamps to the seat post and accommodates disc brakes. Any suggestions? On the racks I have found, the post clamp ones don't accommodate disc brakes or visa versa. Even Ortlieb's rack doesn't. Surprising and frustrating.

Look at the Axiom Streamliner series racks. Axiom also makes seatpost clamps that include upper rack attachment points. The 2 together should solve your problem.

You list the specialized diverge comp as your sole bike under your profile.
Which I find this on the internet
Found another.
EDIT: I have seen those P clips on carbon frames before, so I assumed they were safe. But, I defer to Staehpj1 who has more carbon experience than I have (I have none). Do not use them or if you use them get advice first from someone other than me. [I left the rest of my posting unchanged, I only added this paragraph.]
From the photos it looks like there is a rack mounting point on the rear dropout. You should be able to use just about any rack if you use P clips to strap around the seatstays. By P clips, I mean something like this:
https://www.homedepot.com/p/0-75-in-...1575/202875639
They come in different sizes, I just guessed at 3/4" for your bike.
I used some P clips like that to put an old Rhode Gear rack on my road bike. Two P clips, one on each seat stay and a rack mounting point on each dropout.

I have the current Diverge and the had the previous generation Diverge. I also use the Ortlieb Gravel Pack Panniers. Not sure if you are aware that Specialized makes a seatpost clamp which also has threads for rack mount. I use a Tubus Logo Evo rack without issues. No special clearance is required for disc brakes or mounting clamps. Good Luck.

I wouldn't advise using p-clamps on a carbon frame. That seatpost clamp with threads for rack mount looks like the way to go assuming it is available and fits your frame.
I have often advised using the brake bridge hole as a top mount, but these days bikes are increasingly lacking them. I have also used canti bosses, but again they are not present.
If you hadn't already purchased panniers I might have suggested that you consider whether you might be happy with a rackless system. They work out well for some riders.

The seatpost clamp with holes works well, also take into account that near the dropouts and caliper, often using some spacers will take care of minor issues of rack getting in way of caliper. Don't have your bike in front of me but any good experienced mechanic will help you figure out a way.
* As stae said, NEVER use p clamps on carbon.

Does that seat post clamp above only offer one attachment point for the rack ? Would love to see the other side. If so, I definitely would want the Axiom Trekk Seat Collar w/Rack Eyelets which has 2 attachment points.

I believe this is a Problem Solver seatpost clamp on my wife's road bike. The frame is a 50 cm which cuased some challenges. If you are using pannieers, heal strike might be a problem with the short chainstays.
I made custom panniers with a lot of taper on the forward side. We did not carry much weight. my trek is in the back. I made both sets of panniers.
This was on one of her older road bikes, but it was the same setup

I'd be a bit leary of addig a collar on the post other that the one that is holding it in the frame since I believe that bike has a carbon seat post. The Specialized one a few posats above looks like it was designed for the bike and if so would be the way to go.

With the seat collar, I can use both stays.
Here’s another one

On our tandem I can’t even get the stays near the braze-ons, even with long stays.
I also agree that I wouldn’t clamp something to a carbon post. But a seat collar wouldn’t be a problem.

That pretty much sums it up. I agree that the seatpost collar looks like the way go if you want a rack on the Diverge Comp or other carbon frame with no built in top mount points.

You are using that seat collar wrong. It’s meant to replace the original seatpost collar. I’ve had to use them on my wife’s tiny bikes because the rack stays are too short for the distance to the braze-ons. You can see below in the first picture that I could only use one stay because it interfered with the brakes..

This is exactly what I need!! Thanks. You have the same bike and panniers I have. I don't have the Tubus Logo Evo rack. Maybe I'll get that, given your +++ comments. Thank you.

Its a costlier option, but the Tailfin rack system works really well for this. I use it on my Diverge. Comes with a thru-axle that the rack connects to, and has a connector for the seatpost that works well with carbon seatposts.
