Radical

Guru Oracle

Retired
Top Shelf

The Radical Guru Oracle is a solid reactive bowling ball with the Guru Asymmetric core. RG 2.503 and differential 0.044 at 15 lb. No longer made.

The Guru Oracle 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.
