Where Can I Get A Swinging Arm Spindle

Featured Replies

Hi, I need a 12mm swinging arm spindle to complete my 1972 Bultaco Sherpa. Bultaco UK don't have any and don't know when they will make any?

Alternativley, any one know someone who could turn down a 14mm spindle?

Options

1 Buy some 12mm threaded rod from the hardware/building supply shop

2 Theres a person making stainless steel replicas of many old Bultaco screws, plugs, axles, nuts etc and advertises on eBay

3 Any machining business could thread the ends of a piece of 12mm steel rod for you

Which model? from M10 to M80 used the same part. After that a headed type and then changed to 14mm but forget which model the change over was.
