I’ve sunk 800$ into upgrading my bike and I’m feeling kinda dumb

Please reassure, or roast me… I’m feeling insecure about the amount of money I’ve sunk into this bike. I love it, and I refuse to upgrade to a $1500+ bike until I’m sure I’ll stick with it for more than a few months in the summer. But it’s a Frankenstein of new parts now, I think the only original thing on it is the gear shifter, the wheels and the frame.

I have a 35 year old Bianchi and I’ve had the following work done on it over the past 3 years:

- replaced the pedals
- replaced the brake system
- replaced the seat
- replaced the handlebars
- replaced the tires
- replaced the handlebars and stem, and needed to get new wiring done as a result
- replaced the cassette
- had 2 tune ups, where some of the above was recommended

Am I stupid? I’ve just been operating under the assumption they don’t “make em like they used to”anymore for 800$ so better to upgrade what I have than spend 800$ on a new bike. I’m new to this please be nice 😭
