I picked up my Speedmax CF SLX last fall and can’t imagine anything on the new model that would peak my interest in any way to swap to it. I can’t remember the last time needing the brakes (in a serious way) on the bike, or something with the stopping power of a disc brake. Everything else on the bike is amazing and leaves me wanting nothing more. Now, if it was a CF (non SLX) model that I was riding while eyeing the CF SLX, then I’d have to think long about it as to which one I prefer. I actually like the rim brake version with the “hidden” brakes inside the fork and behind the BB. Can’t imagine throwing a set of calipers and discs into the airflow is anything but a wattage loss (albeit small). Maybe they are tweaking a few other things to offset that. Who knows, but I think we are at the point of progress in some of these bike that are merely marginal gains and ones that we mortals would even feel the difference.
