Lock Down The Lane With The All New Pyramid Fortress

The newest member of the Pro Performance line from Pyramid has arrived with the introduction of the all new Pyramid Fortress. The proven SG Equinox Symmetric core from our Curse line has been wrapped in the new XF Gravitational Pearl cover to offer superior length with unstoppable downlane motion.

The Fortress will be the first Pro Performance symmetric ball in the Pyramid Lineup. With its unmistakable white pearl cover, the Fortress will offer a cleaner look through the front part of the lane allowing for devastating backend angles.

Finished at 2000-grit Abralon with Factory Finish Polish, the Fortress not only looks great but will run through most medium-heavy oil lane conditions.

Lock It Down with the Pyramid Fortress.
