Got a set of the Exotic version of these pedals.

Pretty nice.

Should I grease the axles before I ride them or are they packed with decent grease to begin with?

I didn’t grease mine when I got them.
Stripped them down yesterday to give them the once after using them for 3 months. There was a decent amount of grease inside which was a little dirty but not too bad. Cleaned them and regreased and back as good as new.

You might want to check the pins for loctite/tightness. Strangely I’ve seen a load of pins fall out of a couple of pairs of Exotics, but never the SS equivalent

I have a pair of these. Had them a good year and a 1000 miles or so and not done any greasing or maintenance. Perhaps I should, but they’ve been no bother.
