Bill Haley and the Comets sang how you could “Rock around the clock,” and now you can climb around the Climblock Rotor Wall, rotating climbing wall that promises to put a new spin on rock climbing. Designed in Italy the Rotor offers climbing in spaces with low ceilings and requires no rope. It features holds that can be moved to create climbs of different difficulties, and the speed is adjustable so users can add variety to their training regimes and really “rock out.”
