Triple clamp, Grand Prix, for a 31 mm fork tube (thick). The triple clamp is a steering column part: it connects the front fork legs and holds them on the frame head, transmitting the force from the handlebar.
Replace it if it is deformed after a fall, cracked, or if the fork has play. When replacing, check the steering bearings and the stem diameter: it must match the mounting holes. After replacement the suspension works more quietly and softly, and the vehicle holds its line more steadily.
