The patented ratchet-action closure and speed release clamp of the Pro Elite Clamp is capable of managing any bike frame, up to 85lbs (39kg) and tube diameter up to 2.6′′ (6.6cm). This Pro Elite Clamp replacement head comes with all necessary hardware for installing onto an existing Feedback Sports Repair Stand, and some older Ultimate tri-pods (verify that your existing tri-pod has a 1-1/2′′ tube and the necessary 1/2′′ pre-drilled hole). Patented seatpost / frame clamp features push-button release, ratchet-action closure and micro-adjustability. 360-degree rotating clamp design provides easy access to any part of your bicycle. Rubber-coated, 3.25′′ (8.25cm) wide clamp secures and protects expensive bicycle components and beautifully painted frames. Clamp opening up to 2.6′′ (6.6cm) accommodates even the largest diameter frame tubes. Heavy-gauge steel construction is stout, stable and incredibly durable. Total load capacity of 85lbs (39kg) accommodates service on any bike, including electric bikes and cargo bikes.
