I have a QD hub with a 10 bolt pattern to attach the sprocket for my A10, assuming it was from an A65 I bought an A65 rear sprocket, however it doesn't fit, the ID of the sprocket is a sloppy fit on the hub and the recess to fit over the mounting flange is too small and the PCD for the bolts is a little bigger
There are no markings on the hub
The sprocket works out 10 x 8.15 inches
The Hub works out at 10 x 8.28
