Newbie here, looking at the Liberty CXD as a possibility - and this is why I'm looking at discs. I was tooling around on the Trek 830 I'm using now, ended up chatting with another rider I ran across. With all the hills by me (my commute would involve some spots with 20-30% grade), spots where water and gunk and other stuff gets trapped, so on, he said he went disc and never looked back. He knows how it will handle it every time, and that is why he will never go back. I definitely appreciated his input there.
