I’ve talked about it previously, on a couple of occasions–the full suspension fatbike concept.  I’ve also explained that, from my perspective, a hardtail fatbike is the bees knees.

As seen on Fatbike.com, Carver’s released a full-Ti, full suspension fatbike.

This one is a Rohloff, with a Riise Racing fork and a X-Fusion shock.

The plot thickens.  (I wonder if it’s flexy).  It says clearance for up to 5″ tires, but that must be with a Lefty.  The Riise is built around a 120mm hub, and looks pretty tight with the wheels shown (Marge Lite or Rolling Darryls…60-82mm) and Nates.  It doesn’t look like it would clear a 5″ tire.
