Alison Dunlap designed the ADvantage as a high volume aggressive cross country tyre that corners great on big side-knobs. It also climbs & brakes with authority thanks to the opposing parallelogram center tread design. Ramped center knobs keep rolling resistance minimal & the wide lug spacing sheds mud easily.
