A red, blue and purple colored bowling ball with the Go Time logo in yellow centered prominently.

Go Time

Mid

The Ebonite Go Time is a solid reactive bowling ball with the Big Time core. RG 2.508 and differential 0.054 at 15 lb. For medium oil – heavy oil.

We’re excited to introduce the new Ebonite Go Time, a ball that was an absolute standout throughout testing and has all the makings of a tournament bag staple. Built for medium to heavier oil conditions, Go Time delivers more mid-lane strength and total hook than the GB5 Hybrid, while still getting farther down the lane than the biggest hooking balls in the Ebonite lineup. Its strong, round, and continuous motion gives bowlers a reliable shape they can trust across a wide range of conditions and styles. Just as The One and Game Breaker series have become go-to choices for generations of bowlers, we believe Go Time has the performance and value to earn the same kind of reputation. When you need a ball you can reach for with confidence, it’s Go Time.
