Oooh what a beauty, I am jealous! I would love to have a racer / gravel next to my MTB but I have no room to put in anywhere, our shed is full with 6 bikes already. 😅

Shimano 105, nice! DO make sure you charge the battery with only one derailleur or you will regret it 😆 I've heard in podcasts people with two derailleurs switched the empty battery for the front one so they still had all back cogs to choose from.

I'm looking forward to your first ride experience and also whether you like the twelve speed, I also ride a twelve speed group set but the much cheaper Deore. At some road rides with a certain amount of headwind I find myself choosing between two gears where it would have been nice to have a wider range of gears and I always thought this was an MTB drawback but now I see racers also have 12 speeds. I guess this just takes time to get used to because in the last months with more total distance on the bike I got more used to the fact and it feels less of a problem.

Enjoy! The weather today is great for a longer distance and I will be doing a ride as well.
