Been running a Fat Albert USt on the rear of my winter rigid rig. Was a little negligent about making sure the Stan's sealant was fresh and a little pin hole sent me walking back to the trail after exhauting my CO2. A new dose of Stan;s and all was well, but made me think about trying something new for rear duties. Running a WTB TimberWolf 2.7 up front for some extra squish. Any suggestions for a biggish (probably can;t handle anything bigger than the FA) for the rear. Does not need to be UST.
