Siege introduces Recoil coverstock, an evolutionary coverstock designed to improve mid-lane and backend traction on today’s slicker surfaces. Recoil coverstock combined with the new MACE core delivers both length and strength. The strong traction in the oil keeps the Siege on target. The aggressive hook on the backend increases pin action and delivers awesome hiting power. Take the Siege to batle on difcult oil conditions and raise your game. Siege the day!

Propel Solid Coverstock
Type
Solid Reactive

Introducing Propel™ coverstock the next extension in Brunswick coverstock technology. Propel is a evolutionary coverstock developed by Brunswick to improve the mid-lane and backend traction of the ball on today’s slicker oils and lane surfaces. The Propel coverstock was discovered through testing of new formulation additives and process changes in coverstock manufacturing.

MACE Low RG Core

Mechanical Asymmetric Core Engineering. The MACE™ core has three major benefits, Ultra Low RG core system to engage the Propel coverstock, High RG differential to aid in traction through heavy oil and High RG asymmetric differential to quicken the response time to friction. Designed as a two component elliptical core system, the MACE core is dynamically the strongest asymmetric core ever produced for a Brunswick ball.
