It certainly is a "feature" of the speedplays. I like them enough as pedals (two sided, wide float and crisp clip action) to put up with the occasional regrease and there's something satisfying about squeezing out the old grease. I believe they can be rebuilt as well, but not tried it myself.Whaaaatttttt !!! Campag C Record Carbon Looks - never greased them in 20 years - sweet. Newer stuff, XT SPD's never need touching !!
<tedious_anecdote>If you don't regrease......About 2 years ago I managed to trash the little screw that covers the grease port in a minor off so that it couldn't be removed. They were ancient and running a little rough but I thought I'd ride them sans maintenance through the remainder of the summer and try to pick up replacements in the Autumn sales. On a subsequent ride the bearing seized, about six miles and 100m of climbing from home, causing the pedal to unscrew. Yay impromptu marathon single leg drill!</>
