I recently got a “new” bike to replace my stolen one, and my one complaint about is that the lowest gear is still too high for some of the hills I ride on. Now, I counted 26 teeth on the largest gear on the cassette. Can I just get a new cassette with more teeth, adjust the derailleur and be done?
Edit: removed the long version. whatever. People here don’t know what they are talking about. There is no chance that a chain setup for 26t is going to fit a 30t cassette with a short cage derailleur and survive a big cog cross chained big chainring event unless the original setup was too slack in small/small already.
