I have a Cube Attain GTC, 2021 model, with 105 (mechanical, 11 speed cassette), which I bought new in August 2021.
I've done about 14,000 miles on it since, with no significant issues. I've had to replace most of the drivetrain components at one time or another of course, but that is routine over that sort of distance.
I use it for commuting (twice a week, 31 mile round trip), and regular leisure/exercise rides, in all weathers (except serious gales or ice).
I don't really have any other road bikes to compare it with, my previous bike was a Boardman hybrid, but I am very pleased with the way it handles. Not super-light, as carbon framed bikes go, but not bad at all.
