Looks like parts of my drivetrain are starting to wear out. My current setup is the stuff that came stock on me 2018 Jeffsy, 11sp xtr derailer, E13 cassette 11sp 9-46t, raceface next R cranks and chainring. I will likely be getting a new bike in the next 2-6 months so is it worth it to upgrade to a 12sp drivetrain if I’m just going to sell it in the near future?
The real problem is I’m getting a lot of slipping in the 9 and 10 tooth cogs. Since it is a 2 piece cassette the cheapest option would be to just buy the lower half of the cassette from E13. Would this be a bad idea?
Do bikes with 11sp drivetrains have a much lower resell since everything seems to be 12sp these days?
