Yes - that is the caster kit.
That is a great feature for me - means I can 'parallel park' my bike into a tight space at the rear of the garage - and also can turn the bike completely around!
Right now, it occupies the same space but is 'parked' at about 45 deg.
Also the current process means turning the bike around outside the garage then backing it in to the rear of the garage into the space (which normally involves a little to/fro shunting into the bargain)
With new stand & casters, ride straight into garage, lift bike, rotate and push directly parallel into the space.
Check out the video in the opening post to see how much added versatility the caster kit affords to that end.
And that's before I even get to any maintenance requirement!!
