Deck Concaves
- FK1
- A flat board, with some rocker and a kick tail. Maximum wheel base—29.0 inches. Non-symmetrical nose to tail.
- Flat/FLT1
- A flat board, with no kick tail. Maximum wheel base—30.0 inches. Symmetrical nose to tail.
- K12
- A double kick nose with extra deep concave that adds significant stiffness to a deck. This allows us to reduce a K12 deck’s thickness and weight without losing pop and response. It also features a steep, flat nose and tail. Maximum wheel base—14.50 inches. Non-symmetrical nose to tail.
- K15
- A double kick nose with deeper, smoother concave, longer wheelbase, concave kick on nose and tail and a scoop tail for a more secure foot placement without feeling trapped. A big boy version of the K12 allowing all terrain ripping with the stability of a longer wheelbase. Less wheel bite because the steeper concave goes out to the edge of the board. Maximum wheel base—15.75" Non symmetrical nose to tail. Consider this an upgrade that replaces the K10 concave.
- K16
- This is like the K12 with a shorter wheelbase for smaller skaters. Maximum wheel base—12.25 inches. Non-symmetrical nose to tail.
- KXL
- A kick tail longboard mold with mellow concave and slight kick in nose. Maximum wheel base—27.0 inches. Non-symmetrical nose to tail.
- SP2
- Spoon Nose II, A reissue of the classic Powell Peralta® Golden Age Mold we made the original Bones Brigade’s decks from. A spoon nose kick tail with slight concave on the kick tail intended for making 10" x 30" style decks. Maximum wheel base—17.25 inches. Non-symmetrical nose to tail.
- SP3
- Spoon Nose III, A reissue of the classic Powell Peralta golden age mold we made the original Bone Brigade’s decks from. A spoon nose kick tail with slight concave on the kick tail intended for making 10" x 30" style decks. Maximum wheel base—17.25 inches. Non-symmetrical nose to tail.
