I have a pair of Kenda Honey Badger DH Pro 27.5x2.4 tires for sale. They've been used for about a half dozen park days at my very minimal skill level so they are in pretty darn good condition. The front still looks new, the rear has been dragged across a few rocks. They've always had tubes so no sealant residue.

They are $70 each new, how about $70 for the pair obo?
