Hi all, My rear wheel axle is way too tight (thanks dealer!)
I can get the bolt to turn on the right, but it is spinning the bolt on the left.

Do I just need a 22mm spanner to hold it back?
It has been done up with the left hexagon bolt having one of the points digging a groove into the aluminium spacer/adjuster.

Is it meant to lie flat on an edge? and how easy is it to get a new aluminium spacer?
