Lots of Shimano pedals have a subassembly screwed in with that plastic collar, the bearings are balls & tiny.

SPD SL is a pontoon set flanking a mtb 'spud' cleat, on a hard sole road shoe , is that what you want?

speedplay for road shoes is different from their 'frog' for walking friendly shoes..


time ATAC uses a cartridge bearing , and an oil bushing on the end,,,
