3 Piece Track Spec SL (TS SL)
These are basically the SL versions (Super Light) of the 3 piece Track Spec wheel designs. ADV1 engineering further removed material from all possible places in the design while retaining the rigidity required. The looks are also upgraded and typically make them pretty unique vs. the standard designs. Features include: removal of the assembly flange (visible hardware), use of titanium 2 piece through bolts, full material reduction backpad pocketing and reverse lathe pocketing (material reduction behind spokes) when possible.
