Your early warning system on the lanes. Alert is the first release in an all-new series, built around a low-RG / low-differential symmetric core that delivers a smooth, predictable shape — ideal for medium oil and made to thrive in the middle of your arsenal.

Rev-dominant players get a cleaner, more controlled option that still packs punch, while medium and lower-rev players get just the right amount of ball to round out the bag. Its continuous, versatile motion provides control without sacrificing strike potential — consistent, reliable, and always on point.

Who It's For

• Benchmark seekers — smooth, predictable medium-oil shape you can trust.
• Rev-dominant players — a cleaner, more controlled option that still hits.
• Medium & lower-rev bowlers — just enough ball to round out the arsenal.
