Kye Fitzgerald's larger side bites concept, designed for short to mid-length single fin surfboards. This set of fins is best combined with a small single fin around 6.25". The configuration is ideal for surfers converting to single fins for the first time, or single fin enthusiasts looking to loosen up their favourite board. Similar hold and drive that you'd expect from your tri fin board with single fin flow and speed. Best for smaller medium size waves in the 1 to 4 foot range.
