If I rode hard trails I’m sure I’d see more value in disc brakes. I’ve never worn out a rim in my life. I’m currently running low-end mechanical disc brakes and I find them to be much more trouble than they’re worth compared to my old bargain-basement rim brakes.

I’m curious about hydraulic brakes but I fear the maintenance cost (in time and hassle as well as money) will be too high. Kind of a nonissue for me at the moment, since I won’t likely buy a new bike for many more years.
