May not be relevant to this discussion, but I note that Mud And Cowbells had some news from QBP's annual Frost Bike dealer expo on both the X-Ride and X-Fire
, reporting that the X-Ride will be available in both canti and disc and the X-Fire will be offered as a disc only version for the 2012/2013 season.
I was at FB on Sunday and they had the X-Fire in a few build specs (as well as the new X-Night which is absolutely stunning) but I seem to recall a canti-version. Now that you bring that up, perhaps an X-Fire frameset is what I should be looking towards for cross season. There are too many options and too much time to think during the winter.
