All shimano road mech until the new 11 speed ones have the same parallelogram design meaning they are interchangeable. A 10 speed mech can be used on 6 speed and visa versa.
As I understand it, this means I can use a RD-6401 even though it is supposedly 8-Speed, with a 7 speed setup? Thanks for your help!
