- Balls with the same core
- This is the only ball in the Bowlidex with this version of the Infamous core.
- From the manufacturer
The technology-packed core and strong solid cover produce a motion that is extremely useful and unique. Bowlers looking for a big symmetric ball shape will have to have this in their bag.
The Infamous core is a new design, and while it’s symmetric, it is packed with technology. Hammer is back to using multi-densities within the core to create new ball motions. The Infamous core has a large extra-dense flip block that sits on the top of the core body, and it features a radial disc on the bottom of the ball that helped give the original Obsession extra motion on the backend. There are four densities on the inside of the Infamous, including the famous Carbon Fiber outer core. Featuring DOT technology, which allows you to drill anywhere which makes this ball even tougher.
