The Fin
A 3.7" side bite pair in solid fiberglass, Futures-compatible — the small outside fins that turn a single-fin board into a 2+1.
Side bites convert a single-fin board into a 2+1: the centre fin still does the steering, and the two small fins add hold through a turn and drive off the bottom. The trade is some of the loose, pivoty feel a single fin has on its own, which is why size is the real decision.
This size
At 3.7" these sit in the middle, and are the size most people end up on. Noticeably more hold and drive than the 3.25", still short of locking the tail down.
Construction
Solid fiberglass is the stiffer, heavier of the two constructions — less flex, more direct drive.

What people say
The intent is hold without character change: the fin wakes up on rail and otherwise stays out of the center fin's way. It is the size True Ames flags as its most recommended for longboard 2+1 setups.
The safe middle of the side bite range: pair them with a 7 to 7.5 inch cutaway center on a 9-foot board and let them plant the tail through turns a pure single would wash out of. Size down to the 3.25 to keep a mid-length's single-fin glide intact, or up to the 4.0 for steep, overhead surf.
More About This Fin
A pair of True Ames side bite fins in the 3.7 inch size, Futures-compatible solid fiberglass, sold as a pair. The True Ames side bite range runs from 2.6 inches up to 4.35 inches, and 3.7 is the size True Ames flags as its most recommended for longboard 2+1 setups. The template is upright with light rake, designed to pair with a center fin around 7 to 7.5 inches on longboards and performance logs.
