The Frame Endless 90 mk2 is a precision machined frame, designed for multiple configurations and intended for urban freeride skates like the Seba/FR Skates FR series and other 165mm compatible skates. Building on the success of the original Frame Endless 90, this new version incorporates functional and aesthetic improvements. While retaining the iconic Endless look, the mk2 offers a more refined design with improved power transfer and responsiveness, providing a smoother and more dynamic skating experience.
