It's way too tight at the rear dropout. Right in front of axel is the bolt which holds the hanger and fiddling a cable around that would be way to complicated: 23:55 It's a little long, but you really wouldn't notice while riding and shouldn't be a problem. You can see it pretty good it in the manual if you're interested: media.specialized.com/support/collateral/2024_TARMAC_SL8_USER_MANUAL_ENGLISH.pdf
Yes, still the same. No real point in changing it since it seems to work perfectly and it's reasonably light as well. If you're not convinced you could take up the Bora Hans Grohe approach, they glued in a aluminium tube and use a traditional starnut. They claim the riders prefer the stiffer steerer and it's not that much heavier. You can spot it here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-oSl3A8tHj6U.htmlsi=RBBcglT_qBNnhff4&t=308
Very nice, but a bike like this deserves some light tires. I understand the everything Specialized, but 150 gram less is possible.. Example: Maxxis Highroad (184gr) + TPU(21gr) will result in 368 + 42 = 410 gram
