Chain wrap/cassette Shimano RD 6401 question
I'm swapping components on an old Panasonic DX-4000 7 speed to some 8 speed stuff.(sport exage lx to 600tricolor). I have a Shimano RD-6401 (short cage) and FD-6401 with ST-6400 8 speed brifters and am wondering what cassette to use. I have two choices for chainrings, either a 52/39 or 52/42. I'm thinking of a new Mavic open pro/ultegra wheelset, but not sure on that yet. The VeloBase website says the RD has a max of 28t for cog and also 28 for chainwrap, any thoughts on what to use? Does a 12-26 with the 52/39? 11-28 with the 52/42? something else??
