Introducing the Technica by Quest Undercar. By providing the perfect balance of tech-friendly features with advanced technologies… the Technica will be the technician's choice for servicing difficult assemblies. Dual polymer bead rollers with hand controls provide fast and effective bead loosening, while the tilt-back column with leverless demount head provides the rigidity and durability needed to handle the most challenging sidewalls (without scratching the wheel). The center clamp design enables technicians to access the top and bottom of the assembly without risking branding or marring the wheel's surface.
