I just bought a hybrid cannondale 400 and I was doing some internet research and i cannot find any replacement wheels for my bike. theres nothing wrong with the ones I have yet.this is my first hybrid bike and i love the ride and all. its just what happens when my wheelset isnt any good anymore do i dipose of the whole bike? because it seems like that cause i dont understand which rims I can put in replacement of the old ones.anybody can give me some insight to these new 700c wheels.I cannot find them anywhere. I think a mavic speedcity might be a wheelset but not sure.and its expensive too dont like that. anyway any help out there. thanks
