Mitch thanks for all of your help here.

I'm on a 2020 Checkpoint with the carbon seat mast cap (believe same as the 2020 Domane etc.etc.)

I've purchased (3) options

One is the 7x10 Trek clamp, another the 7x9 Trek Clamp (both found via https://www.trekbikes.com/us/en_US/equi ... s/p/06096/ and lastly is this weird thing i found on https://www.ebay.com/itm/302465271084 claiming to work

Of these, would any work with Specialized S Works (or other 7x9 carbon railed saddle)? Would hate to damage my bike or saddle doing it wrong but surely one of them has to work right?

I have also heard that some etape can help make 7x9 fit the 7x10 clamps too....

Would love an "official" option from Trek, I'd gladly pay. Otherwise looks like I'm stuck going Fizik or something else that does 7x10..... bummer.

I'm trying to find the damn 7x9 or 7x10 clamps for my Emonda seat mast so I can use a carbon rail saddle. It's ridiculous how hard this is. Why would Trek not provide all the clamps with the bike??

The trek website lists stores near you that have the clamps in stock. That's how I got my clamps for my Berk Lupina saddle (which has been on order since March...).

Why do you think the 7x9 Trek clamps (in silver) won't work for any 7x9 carbon saddle? They are quite literally designed for any 7x9 carbon rail saddle.

Yeah I've been calling all of them and no one has them even though the Trek site shows that they have stock. It's a big mess.

I (perhaps I correctly) thought Mitch and few others said it's not comparable with mine. It looks quite different to the current clamp tbh.

I'd be stoked if it works !

The 7x9 clamp would work with any 7x9 rail of any material, so you'll be good to stick with that for your saddle, this is part #406923. The silver one in your photo looks like it, but if it is the stock one, then it would not be 7x9.

Thx man! That's the one.
Any concern of support / leverage given that it's triangular and not more square like the 7x7 I've got in there now ? (Only cause I use this bad boy for gravel)

No concerns at all. It's a proper product. I've been using the identically designed 7x10 clamp on my Domane SLR with a Bontrager saddle for 3 years now. No issues at all.

here she is installed with a S Works Power Mirror (7x9)
seems to fit perfectly!

Mitch, any idea what the Trek PN for the actual hex bolt is (mine is quite rusted)
Thanks!

How do you like the power mirror saddle?

I want to replace my Bontrager Affinity Pro saddle (the size is a bit too wide for me). I've had the Berk Lupina padded on order from starbike for ~4 months now without any ETA. Thinking of getting something else instead.

I have to be totally honest, I thought the whole thing was so hyped and over expensive before I bought it, but i freaking love it. I had a power mimic before which I liked but would get sore after a couple hours, this one feels incredible all day at the moment. I haven't tried on gravel. yet, so might be a different animal but I love it.

I don't have an individual p/n for that bolt, but if you send me a DM with your info, I'd be happy to get you a complete hardware set.

Hey all, just wanted to make an update in here about the Domane.

For 7x9 saddle rails, you can now use part number W5256105 for all 2020+ Domane SL and SLR seat posts. This was updated a bit ago, but I didn't update you sooner.

Cheers!
