Dune GripWe made the Dune as we wanted to design a single clamp grip with a consistent grip pattern, that gave riders a different option from our other single clamp offering, The Format. It features a thin diameter and rounded diamond knurling for traction without a harsh bite. At 15A, the compound is soft with a moderate wear life. While still tacky this gives increased durability over the Supasoft version. The Supasoft compound is the tackiest we offer (9A)
