40T on an Aero?
Does any know whether a Ti Aero can use a 40T large cassette sprocket? I know Dan uses a 36 on his Aero.
Shimano's 11s mountain cassettes are supposed to fit on a 9s cassette carrier. So this looks like a minimally expensive way to change to 11 speed. As far as I can tell, 11-40 is Shimano's smallest 11s mountain cassette. The 11-36 and smaller cassettes are road cassettes and require a wider carrier (on a new hub).
