In the late 70s and early 80s, Santa Cruz led the charge from flat decks with little or no concave to the infamous tech concaves of the late 80s. Early 80s concave is based off of this evolution, with defined, mellow side-to-side concave and slight tail kick that was found on Santa Cruz's Street Skate, RS/C, and other pro models. Hand screen printed and numbered at NHS, Inc., and laser etched deck top reissue logo. Measures 10.03" x 30.33" with a 15.94" wheelbase. Comes with Core trucks, 58mm 97A wheels, Amp abec 5 bearings, Black Diamond Griptape, risers, and hardware. Core trucks are light weight and feature heavy duty aluminum with grade 8 steel kingpins and axles, as well as USA made bushings and pivot cups. 58mm 97A are the perfect wheels for both street and park skating. Like the name states, Amp bearings are stimulants for your wheels! Light synthetic oil, Delrin Crowns, and Rubber Serviceable Shields are a few of the things that makes these bearings one of the best Abec 5 rated bearings on the market. Arrives un-assembled which allows for customization and a feeling of accomplishment. Skaters love building their boards! Easy to assemble!
