Is it common for the rear mounts to need facing and will warranty cover it?
Perhaps an interesting read:

I won't pretend to understand all what is written here, but I like the conclusion. :D

In my experience with enough patience it's generally always possible to align disk brakes, even when the disk is a bit out of true.

been using this type alignment tool Image
since day 1 of using disc brakes and never had an issue! Put it through, squeeze brakes, tighten caliper, voila.

SL8 has been one of the easier ones actually. On some bikes I had to do it 2-3 times tightening the bolts suuuuper carefully and gradually so that the caliper doesn't move fraction of mm in the wrong direction while tightening and start rubbing again.

BMC Roadmachine I got back in 2018 was the WORST offender.

Well I've been doing some more investigation, either the top or bottom of the mount isn't square as they aren't square to each other. With a set of verniers over them, there's a good 0.1-0.2mm gap on one side.

Even once torqued I can get a 0.05 feeler gauge under one side of the caliper

Additionally there are witness marks on one side of where the bolts do up.

Definitely out, frustrating that whoever built it ignored this as they must have had an absolute shit time aligning with new pads.

With new swisstop pads, it's not even possible to align them without some contact on one edge. With the outside bottom lightly kissing the disc, the inside top has the tiniest slither of clearance.

Sorry to hear. I know it's a long shot as UK is HUGE but are you by any chance close to mapdec cycleworks? He seems to fix these issues often and makes videos / shorts on youtube about it. He might even be able to contact specialized for you to see if warranty can cover it.
Worst case, if you contact, maybe he's able to recommend someone close to you? Just a thought

Is that Gap normal?
Currently building up my Frameset and just wanna make sure I didn't do something wrong...

You probably know what you're doing and have it just resting on the top tube, but just to make sure, be careful about not clamping the bike there.

For what it's worth, with the EXS Aerover barstem (with the SL8 spacer kit), the gap is smaller.

Yep -hopefully I do :D. In german is a saying: "After tight comes loose".
Its only ever so slighty tight that it wont move. I could move, so not tight at all.

But nevertheless: Thanks for the info! Build comes along greatly. having the "semi full integration" is a bless to work on, compared to canyons damn T Shaped Handlebar. I cutted the steerer tube about 1mm "short" so I needed to sand that one mm down (what a nightmare :D) The saw I used would not help here. But anyhow. After 30mins it was done.

To be honest: I normally clamp bikes that way - I kinda just dont like it on the seat stay (maybe because the bending moment with a front wheel installed? Dunno. Never felt "ideal" for me. But thats maybe (another maybe :D) because of our MTBs where the seatstay starts making nose with full weight.

It is normal and apparently specialized make like this to accommodate for thicker paint schemes. I have sanded my compression ring to reduce the gap to something acceptable. The process I have done is described starting on this post viewtopic.php?p=1860339#p1860339

Build ready!
Any recommendations for some weight reductions? The Garmin mount seems very heavy.
Currently standing at 7.1kg. bottle Cages are Leftover from my Aeroad. Looks quite nice and with 35g per Cage reasonable lightweight.

Quite heavy? What is the weight of the wheels?

just first look and comparing to my setup
Bottle cages I have Elite Leggero save 50 grams
Cassette Duraace 11-30 saves 20 grams
Saddle I have Alpitude Gardena save 90s grams
Wheels I have Farsports carbon spoke 50mm save 200 grams
over your setup.

Ofcourse you be the judge on what's worth it pricewise!

You could always ride as is cause it looks badass and I'm sure it rides just as good. 7.1kg is "heavy" for ww but in all honesty, should be a delightful ride still.

Take my word with a grain of salt though. I'm less ww every day. Just raced Pescadero Road Race here in California last weekend. Seeing 20 year old kids ride away from me while doing 400 watts with their 8.3kg bikes puts perspective on things.
(Helps that they weigh 120lbs)
