I have two speed king pedals, one ive had since about 1992, I use light machine oil and it never squeaks, another I picked up in a yardsale is unusally original and I actually had hoped that it WOULD squeak,(just for an "unrestored vibe" and it does not. I just cleaned it up a bit and who knows maybe it will now.by the way, one of my pedals has rubber bumpers on the two parts that hit the bd hoop( the tabs with a hole on either side of the toe clamp, they are held in with brass brads, I have nevers seen this before, was this a mod or is it original?
The optional bumpers were on SK pedals produced in the 80's and 90's. Ludwig used wider BD hoops during that time, and the bumpers allowed the modified version of the SK to work with the narrower hoops of other manufacturers.
