Front axle15mm→for conversion to 17mm
J's OEM wheels have 7 holes in the discmount, and many of them have a small outer diameter disc I didn't like the dirt accumulation in the shape of the wheel
So, I changed the Axle to 17mm with the replacement of OEM wheels for the models with high expansion capability Z's Outer tube is old fashioned mount structure It's great that you can change the axle diameter with just one clamp change
