Hey! Welcome to the forum! Believe it or not.. I actually have worked in a shop that sells Bianchi, and have personally worked on the Via Nirone. Its excellent for what you are trying to do, and leaves plenty of room for improvement in future rides. I haven't actually weighed the frame personally, but I do know it isn't light, and with the carbon/alum fork my guess is the whole module is close 2000gr. Thats a really rough guess. As far as the rest of the build, there is room for improvement there as well but I would argue that you don't need to yet. Wait till you get that Cat 3 upgrade
lol jk, but I do think its a solid intro bike.
