Curious why 53223 shaped inserts don't get much of a mention. Why are they less popular than the sponge 53255 inserts?
I have already ordered the 53255 hard inserts as recommended by Tony and am happy with them, just curious.
And what is the diff with the older UJs 53205 vs the newer assembly UJs 53597?
I can't wait for the next race - M01 to M05 move
