Hello all, I want to upgrade my trek 1.5 from 9 (11-26) to 10 (11-28) because I was told (nashbar tech) that I would not have to replace any other components. When i called back to place the order spoke to a different person who said that I would have to change all the components to do that. Who's mistaken?
And if I do have to switch all the components to match I might as well go to the 11's no?
