- Speedball Colored Bats are made from injected molded plastic. - They are less susceptible to warping than other bats. - The bat pin holes are on the underside of the bat. - The pin holes are tough and show little wear over time. - Easy-lift rim makes it easy to get your fingers under the edge and remove the wheel head. - The unique design allows a snug fit for all wheels that use 9" and 10" pin systems.
