Yep. Likewise with the front wheel, there's nothing that will undo that spindle either. You'll need to get yourself a 22mm socket for the rear nut and a 14mm hex for the front axle � I carry a 14" long 3/8" breaker-bar as it's lighter than a ratchet handle and offers the leverage needed to undo the rear nut (105nm torque).

Worth investing in a torque wrench for home-use if you haven't already got one.
