Product Description
Turbo Urethane Solid Thumb Inserts are designed to enhance bowling performance by providing a consistent, smooth, and comfortable thumb release across various bowling balls. Made from 100% urethane, these inserts act as an insulator, protecting the thumb from the tacky and abrasive textures of modern reactive and tech resin bowling balls, which can otherwise disrupt release and timing. Available in standard sizes (1-1/8”, 1-1/4”, 1-3/8” with a 2-5/8” drill depth) and an oversized 1-1/2” option (3” drill depth), they feature a pre-sanded outer surface for easy installation and are favored by bowlers for their quick release and clean finish. Pro shops appreciate their ease of cutting, carving, and finishing, while duo-color options help consolidate inventory while expanding color choices. Turbo, the first to introduce urethane solids, remains a leading choice for bowlers seeking reliability and uniformity in their grip.
