• The b-pivot is tucked in very close to the stop for the cable-outer.
• The various body and parallelogram plates have polished edges and lush chrome.
• The hanger plate and most of the bolts are also precisely finished and lushly chromed.
• The roller over which the cable runs is chromed.
• The pulley cage is 43mm long.
• The pulleys have black plastic 'tyres'.
