ENGLISH WHEEL TOP ROLL HOLDER.
Roll diameter 200, width 75 mm (~8" x 3")
Pin hole diameter: 20 mm.
Integrated pin spacers. A small thing but a joy.
If you disassemble/assemble the top roller more often, your task will be easier.
No need to look for spacers on the floor :)
For the indicated price you buy what you see in the photo above.
