I owe my neighbor a favor - he has been kind enough to plow my driveway several times over the years. The other day he dropped his bike off, and asked that I replace the cassette and chain. His bike is all Shimano, including the shifters & derailleur. He had purchased a SRAM chain and a Campy cassette. All are 10 speed components. How interchangeable are these components from 3 different manufacturers? I don’t want to spend 1/2 a day trying to adjust the shifting.
