Sigma Tour

2 Read Reviews

THIS BALL IS RETIRED AND NOT AVAILABLE FOR SALE.

The pros asked us to maximize the proven Sigma core with a new coverstock to add length and create a stronger backend motion with continuation on medium oil.  MOTIV engineers delivered with Atomix Reactive technology.  The resulting pro-level ball is a house-shot killer!

For highly competitive bowlers, the Sigma Tour will chase the pattern and still corner very hard on the backend with the angle needed to provide strong continuation.  The Atomix Reactive cover creates incredible backend motion and the low RG core provides a controlled breakpoint for high rev bowlers to maximize pin count.

    Great ball

    I've been throwing this ball weekly for the last 6 years and even though I don't take the best care of it, I'm impressed with how well it still reacts even with a season worth of oil on it plus whatever tournaments I might bowl. I would recommend it but sadly it's not produced anymore.

    Versatile

    One of the most versatile balls I've ever thrown. From being able to throw a stroker line on wet lanes to curving the lane on dry lanes it's helped my average rise all without having to change my rev rate or ball speed. The ball motion is extremely predictable throughout this range and the backend stays snappy no matter how deep I have to throw it from.

    I would recommend this to a friend
