Can you get 7sp powerlinks? – only 8, 9, 10 are available on line.
Will an 8 speed powerlink work with 7sp chain?
Will a 9 speed chain work with a 7 speed cassette? I’m sure 8 will be better.
I just found out a 7 seed chain can’t ne repaired with a 9 speed link – I know I was being a bit hopeful and it is obvious when you know.
Sheldon Brown’s words regarding chains:-
“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. Thus, you can use a “9-speed” chain with a 7-speed or 8-speed system, or a “10-speed” chain with a 9-speed system. Since the chains designated for more gears are usually more expensive and don’t last as long, this is not the ideal approach, but it’s perfectly workable.”
