Asa cum si numele sugereaza, Dartmoor Revolt Cassette, reprezinta versiunea mai permisiva a gamei Pro. In mare parte este acelasi butuc cu mentiunea ca are doar 24 puncte de angrenare, 6 clicheti cu un singur arc si 4 rulmenti sigilati situati in interior. Acest butuc foloseste acelasi sistem clasic de angrenare, axul interior, corpul si conurile sunt din aluminiu 7075.
