The original cassette, a Shimano Mega Range (13-34) says ZH37 on it. Can I replace it with an HG50 (7 speed of course) ... either 12x28 or 14x32? If I can switch, will the rear derailler need adjusting b/c of the different cog sizes?
Right now it is like having 6 speeds because the mega range jumps from 24 to 34 which never is smooth when riding.
Thanks.
