Osera

The Osera was designed to create a single fin that offers neutral feedback. The consistent surface area from base to tip provides balanced response through turns, while the arcing template allows the fin to bend under pressure—delivering a predictable flex that enhances control at higher speeds.
 
This fin works great with side-bites. Add 3.5" sides to the 7.5" or 3" side-bites to the 8.25" to increase stability and control.
