I own a 3×7 bicycle with Shimano shifters. Got my delivery yesterday and tuned my rear gears using https://youtu.be/UkZxPIZ1ngY?si=5vwriVNeHdkeEpYa.
I tuned the rear wheel with the front gear mostly on the largest disc or the second largest disc. Now that I start using the smallest front disc, I’m noticing that the chain is grazing the rear wheel. I haven’t tuned the front gears yet since the shifting worked pretty flawlessly so far. But I’m pretty sure that the front derailleur tuning won’t have much impact on my problem.
Has anyone here faced this and How can I resolve this problem?
