With needing a new chain and possibly cassette, I'm at a bit of a juncture with my main commuting setup- to simplify I am considering swapping the current setup (9x3 105) for a CUES 1x setup (and selling the old components). Assuming price is a wash (After selling the old components) and ignoring differences in drop bar / flat bar (no drop bar cues stuff yet), what is going to be the most reliable / with most mileage from drivetrain?
Use case will be year round 5-day a week commuting in a place that uses salt, full fenders, studded tires in winter, with occasional long-ish recreational rides (<50miles a day). I did just fine with 1x11 commuting in the past as far as gear ratios etc. I kind of hate having a front derailleur, but it's kind of a necessary evil with my current setup.
