    Product Description

    The Radical Guru Oracle bowling ball features the same core shape as the original Guru but with slight density modifications. The Guru Oracle bowling ball has core numbers of 2.503 RG, 0.044 DIFF, and 0.018 INT DIFF. The Original Guru was one of the balls that put Radical on the map. It was known for its versatility and strong sweeping motion. With the addition of the industry-leading HK22C solid cover, we have created a modern version of the original legendary Guru. Expect lots of hook and lots of down-lane motion. The Original Guru was a staple in everyone’s arsenal, and with all the requests for a remake of the Guru, we expect the Guru Oracle to be readily accepted.

      Guru Oracle

      Posted by Robert way on Oct 7th 2025

      Guru Oracle I’m a left handed bowler. My ball speed is around 13.5 mph. My Rev rate is around 275 rpms. I recently punched up this ball. My layout choice is 40 x 4 x 30. Very close to the most versatile layout suggestion on the Radical bowling website. For me this ball is a beast on the backend. The backend is strong. Not flippy. But aggressive backend motion. For me this core and layout and a loopy roll to it. That helps it get thru the fronts. And with the aggressive cover. Wow great backend hook. I think it is a great addition to the Radical line. I use my on house shots and the longer patterns. If you don’t owe one. I suggest you to try one out. Thanks, Robert Way
