The rear shock on my RD04 is really harsh at holes and bumps, and it goes thru the whole bike.

Its feels like the compression damping is too hard. I have tried to adjust it, but I can’t feel any difference.
I have 30 mm free sag, and 70 mm rider sag, so the spring should be ok. (from the 10%/30% rule, I have calculated the spring to be 9% too stiff, but I don’t think this is causing the problem).

My RD04 is modified a bit, so the fully fueled weight is 210 kg, and the weight on the rear wheel (with 10L missing in the tank) is 100 kg.
The big question is now: Should I go for a rebuild of the original shock, or should I find an aftermarket shock in the cheap end (YSS, Hagon, Wilbers Ecoline)?
If it is going to be a new shock, I will spend around 400€ on it.

It is the best gravel road and offroad performance and comfort I am looking for. I almost only use the bike for gravel roads and offroad, and road transport to find it ?

I put a Nitron on the rear. See my report here on Nitron shocks. Initially did the work on the RDo7/7a. I was so pleased I had one made up for RD04 as well.

Transforms the bike. I went for one without the external hydraulic ride height adjuster for the RD04

Thank you for your answer Paul-S.

The Nitron looks really good, but i am looking for a bit cheaper rear shock. My currently preferred candidate is the Wilbers Ecoline (400 euro).

But before I can order it, i need to know how much lighter my RD04 is comparred to a fully fueled standard one.

My RD04 have a fully fueled rear wheel weight of 105 kg.

Can anybody with a standard RD04 help me with a fully fueled rear wheel weight?
