Stefan, Many thanks for the reply - I can see now that if I had
clicked through I would have see the different descriptions. Is
there any particular reason to go for the roller bearings over
the poly bushes? Of just a personal preference thing! Thanks Ian

Both work.
My first axle had the poly bushes because bearings weren't an
option then. I ended up replacing the bushes with Oilite but
that was probably my doing. The thing to remember is that you
want the yoke and the "anti-crush" tube to all be tight together
(ie the bolt should pull them tight against each other and move
as one unit). You can then tweak the bushes if you need to.
The axle set we bought (for Marek's cyclekart) has the bearings.
