I'm no expert in this era of pace forks, I'm not sure if my ones have springs or elastomers, I'd assumed springs as I thought rc35s were the last elastomer forks, but I could be wrong so don't take my word for it.
Springs are fit and forget really, but only good for forks with damping otherwise there is no control over rebound. People say they pogo, but in my experience when I've replaced elastomers with springs on undamped forks like rc35s, I can't say that was my experience.
Elastomers do of course deteriorate over time, but plenty of options for replacement on here, online and you can buy rods of elastomer to your preferred hardness and cut to suit, which I've also done in my past with older pace, manitou and Judy. Elastomers have damping qualities of their own, they squish, then rebound and unlike springs, don't bounce or pogo.
If I get time, I'll pop the lowers off and see what's inside.
