Parabolic Stringer Configuration

Parabolic stringer configuration places the reinforcing stringers along the board’s rails instead of its center, creating a progressive flex pattern with enhanced torsional control. This layout distributes load and rebound energy across the outline, allowing the board’s center to flex while the perimeter maintains structural tension. Often used in EPS cores and epoxy laminations, it increases drive, spring, and durability under compression.
Shapers refine parabolic stringer designs through reinforcement balance, carbon placement, and precise alignment to achieve flex synergy between rails and centerline.
