As I found out the hard way there are two different kinds of rear disks for the Valk
But may or may not be an issue ... I think
Lightweight - The lightweight rear disk has been shaved in the center around the mounting bolts
its really lighter and its the one I have that needs to be replaced (its down to about 5.50 mm the pads actually stick into the upper and bottom lip making it slow for the pads to compress away from the disk!
Here you can see that the whole mounting area was shaved down and the mounting bolt holes are not recessed. Picture shows the bolt head sticking out

Here you can see its been shaved down to around 3mm

Heavyweight - The one I order from Pinwall. Its not shaved and it way heavy, its the same thickness from top to center.
Here you can see the mounting bolt holes are recessed as to make the bolt heads fush with the disk

So what does this mean for me???? Will I have issuse??? Am i in trouble
