The 1.9" Nubster / Bonzer Side Fins are compact stabiliser fins designed to fine-tune control, hold, and flow in modern performance setups. Commonly used as Bonzer side fins, Nubster trailers, or mini quad rear fins, they provide subtle resistance without adding drag or stiffness.

Constructed from durable black Pro Glass, these fins offer a consistent, medium-stiff flex that maintains speed while improving directional stability. Their small size allows the board to remain fast and lively, while enhancing confidence through turns and high-speed sections.

Ideal for surfers looking to dial in their fin setup rather than overhaul it, these fins are a powerful tuning tool for a wide range of boards and conditions.
