changed wheels today , what is this bolt , cant see what it is there for ? at the bottom of photo .

ho its on the front , none on the back.

Would imagine it's there to hold the disc onto the hub, tho' normally would expect to see a countersunk set screw that sits flush with the face of the disc.

It's to stop you fitting a rear wheel to the front, if I remember right.
