So far as I have read in this thread no one is mentioning the Cannondale Slate with the Lefty front fork. My gravel bike, a Ritchey Outback, obviously has no suspension. I don't think that it needs it. If I am going out on some very technical trails with big rocks and drops, I would take my full suspension mountain bike, Tomac Revolver. But that said, the weight and slower feel of a suspended mountain bike is what makes the Ritchey so much more fun for me.
