Title: Fork identification
Post by: watts on 29 Jan, 2025, 16:16

I have a ZM M20 frame and I am wondering if they are correct as they do not have a lug on the front for the mudguard stay?

If it is not does anyone know what model they come from?

Thank you

I haven't seen one like that. The correct one will have a flat lug front and back. Both lugs will be threaded.

Here is a picture from the rear on the brake side it has a bolt to stop the plate rotating and not a piece in the inside of the leg.

The correct brake side have a lug with a hole in it. A spigot on the brake plate should go into the hole as an anchor. The stay lugs are flat and threaded one facing forward and one back.

The tax disk holder could have been a brake anchor point.
