Good first bike......esp if fan of just doing zone 2 90% of the time and no surges/sprints of any sort....i mean you can surge/sprint lah, it still would be plenty fast enough for you or me (it's our leg strength and neuromuscular that really matter, plus Creatine lol ).
Can still easily maintain 35, 40kmh one lah...all those tubes on the bike have aero designs on them (better than normal round tubes), and definitely can get to 45-50kmh with a bit of downhill. Get 2 of those aero type water bottles, so many on TB. What matters the most is the position on your bike, ie how low and aero can you get + maintain over XX or YY minutes....your back and core strength and triceps and a bit of front deltoids....need to strengthen a lot, ,much more than the typical strengthening that you see in running.
But important thing is, ask them to change the tyres to the ubiquitous Continental GP5000....just leave the butyl inner type in there, no issue and confirm durable / 耐用 and fuss-free. If you are careful and plan your routes carefully and do proper routes with good roads, vast vast vast majority of the time wont even puncture.
If it works, it works and nothing to tune esp since it is electronic shifting there is nothing to tune etc, dont bother messing with this and that.
Then if wanna "upgrade", just sell it.... ...which i'd deduce that'd be 12-18 months for you, if you intend to take the hobby to the next level. Dont bother to mod or change this/that, coz sometimes the tolerances of Twitter might not be very good......just more headaches.

BTW one thing, the crank length, i think for your height......see if you can spec it to be 165mm long. This is esp so if you always like to be in the aero tuck position. It says can use Shimano 105, confirm can be changed to 165mm, just top up nia.
