(Set of 4) These runners come in a set of four, and already have 19° of cant incorporated in the fins above the tabs — no need to adjust the angle, we've done it for you.
(Set of 4) These runners come in a set of four, and already have 19° of cant incorporated in the fins above the tabs — no need to adjust the angle, we've done it for you. These fins are the perfect complement to the Bonzer center fin for the classic 5 fin setup.
Front Fins: Height: 2.37" / 58mm | Base: 4.75" / 121mm | Area: 7.60"² / 49.07cm²
Back Fins: Height: 2.75" / 70mm | Base: 5.5" / 135mm | Area: 10.30"² / 66.48cm²
The heavy cant and low, delta outline channel water along the bottom contours and feed the center fin, so the cluster works as one system rather than five separate fins.
On a Bonzer bottom paired with the matching center, the runners give the board single-fin-style line-holding with serious drive and projection through a section.
Buy these to complete a five-fin Bonzer, paired with the matching center fin on a Bonzer-bottom board, where they deliver fast, drawn-out trim with serious drive and projection. They are not interchangeable with regular side bites and will not improve a board that was not shaped for the system.
Set of four rail fins for the five-fin Bonzer system, designed by Malcolm and Duncan Campbell and built by True Ames in FCS-compatible solid fiberglass. The fins are low, delta-shaped and heavily canted, sized as a smaller front pair and a slightly larger rear pair. They are positioned so the leading edge of the Bonzer center fin lines up near the trailing edge of the rear runners, and they pair with a Bonzer center fin on a board with Bonzer bottom contours.
The review contrasts the runners with standard side bites like the 2.6" set, which add a little rail grip to a 2+1 board rather than functioning as part of a five-fin system.
