505A Product Notes

Description

Manufacturer’s Intent: The second launch in the 5 series, the 505A, was designed to be more angular at the breakpoint. If the 715A was too aggressive on the lane patterns you bowl on, then the 505A will be a great choice. Each new ball from Track will include a microfiber cleaning pouch with instructions on its use.
