Schwalbe Big Betty 2.4 wire bead. I have googled and looked everywhere. So where can I buy a set of these? I want to try them for everything but wet and mud on dh. Also I have 823s and might try tubeless but I'm afraid of dents in the rim. I usually ride eastcost rocks (snowshoe,windrock), I'm 165lbs, and I ride fairly light on my 08 devinci wilson 4. Is the size and weight the as minions,high rollers, or ardents? Thanks.
