Hi everyone, this is my bike and I bought it 5-6 years ago secondhand for only 50€. Until last year, it was sitting in the balcony and last year, my friend and I have decided to make a small tour with our bikes. So, I took it out, changed the brakes, shifters and cables, tires; put pannier racks to the back and front. Since then we made 3 small tours, 1200 km in total. The bike is a tad small for me, I am 188 cm and it was giving me lower back pain on long rides so I decided to upgrade flat handlebars to butterfly bars for more upright position. I did 300 km with these bars in 3 days and I felt more comfortable.
My dilemma is this: I know my bike isn't the most durable bike for longer trips and after every trip, I feel like I need to fix something (as you can see from the various tapes). And I already spent like 200€. The drivetrain doesn't sound good, and rearhub seems like it's slowly dying. Should I spend more money on this bike and upgrade the components or should I buy a new one after this one completely fails? I have been eyeing Trek 920 which I can get around 1100-1200€ or Giant or Cube new for similar amounts. For now, we will only do sub 1000km tours at most but maybe one day I would like to make a longer one.
