The bearings in my V8s are a bit ropey now, despite regular stripping and re-greasing they’ve only lasted 12 years.
(Loctite 7840 degreaser, Finish Line grease)
If the bearings are tight from the factory, they’ll wear quickly and your pedals won’t last.
Whip ’em apart, clean and degrease, repack with good quality grease and they’ll last. You can’t do that with V12s, they just wear.
Degreaser and lube are cheaper than new bearings and bushes.
