My bike is rather old and needs lots of work. I am trying to understand how to replace things myself slowly other than through a professional (to save bit money).
A bike company said that I need a new cassette now (I agree), so I bought a cassette removal tool and removed it now.
On Amazon, seems a 7 speed freewheel is much cheaper than a 7 speed cassette. I am fairly confident that my current one is cassette, and just wondering if I have to buy a cassette or for the new one I can go for a freewheel? Will it be much more extra work for people without much experience?
