7-speed, 8-speed 9-speed, 10-speed?Component manufacturers like to sell you lots of new parts, even if you don't need them. This has led to much confusion as various parts are labeled as if they are incompatible with other parts even though they are not.
The following parts ONLY are "speed specific":
- Indexed Shifters These need to have the correct number and spacing of detents ("clicks") to match the system they'll be used with.
- Cassettes It is really the cassette that determines how many speeds you have in back.
- Chain As you go to more sprockets on the cassette, you need a narrower chain. However, using a narrower chain with an older system rarely presents any problem.
