Frannie is a 2019 Salsa Vaya.

Steel frame with a Shimano 105 drivetrain. We roll tubeless. She typically hauls between 20 and 40 pounds of gear depending on the season. I used to ride carbon, but once I hit my 40s every ride started to hurt a little more, so I moved to steel. Unloaded, the frame weighs about 19 lbs, but it handles smooth as silk.
I would spend 8 hours a day on this thing if I didn’t have a job.

Dat azzzz
My brother has a similar type of bike that he uses for almost everything for over the last 25 years.
Granted, it has had lots of maintenance over the years and it’s a little bit a ship of Theseus situation with tires, brakes, chain, sprockets, etc, but the frame and wheels, steering bar etc. are still original.
Good bikes be good bikes for life
I have a 20-year-old Trek 4200 with about 70K miles on it. The thing is fucking immortal and it wasn’t even close to being a top-end bike in 2006 (I think it cost around $500 new). Drivetrain, tires and brakes are the only things I’ve ever replaced, obviously many times over.
