Fin configuration: One 1.3" Disorder fin on each end One 1.3" Disorder fin on each end. The Phriction is a pro-model performance on a budget. New for this year is its E Core construction, which means a sealed wood deck for no more warping or cracking like traditional wood decks. Combine this with a radiused sidewall and our super tacky pad material inspired by pro-model concaved decks, and you have the perfect fit. It was designed by Scott Byerly, Brian Grubb and Brandon Thomas.
