Hello and welcome to the forum! I am new here, also. It looks like your new machine is a good, solid entry to the world of road cycling. As far as maintenance goes, have someone who is familiar with the mechanics clean and tune the bike while showing you how to do it. You can also take repair/maintenance classes at a local bike shop (if you have one nearby that holds them). Once you are familiar with how everything works, maintenance will not be a problem.
Best of luck out there. Stay safe and keep the rubber side down!
