FCS II RM Rob Machado Side Byte (Set of 2) We are listing this at the current lowest price on the used market. This is a popular model, so it's first come, first served. [MACHADO SIDE BYTE] Recommended for use as a single stabilizer with the single fin MACHADO SINGLE, designed by Rob Machado. Pairing it with the MACHADO SIDE BYTE allows for smoother turns and finer pivots. It is also highly recommended as a quad rear fin when paired with slightly more upright keel fins. [Fin Size] - Base Width/Approx. 85.7mm, Height/Approx. 77.6mm [Material] - Performance Glass (PG) Thank you for your consideration.
